Normalizes to peak envelope. * Working DBPSK mod/demod (works fine) * Working DQPSK mod/demod (works, but still needs more work) git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@3662 221aa14e-8319-0410-a670-987f0aec2ac5 --- gnuradio-core/src/python/gnuradio/Makefile.am | 1 + .../src/python/gnuradio/blksimpl/Makefile.am | 6 +- .../src/python/gnuradio/blksimpl/dbpsk.py | 370 ++++++++++++++++++ .../src/python/gnuradio/blksimpl/dqpsk.py | 370 ++++++++++++++++++ gnuradio-core/src/python/gnuradio/blksimpl/gmsk.py | 289 ++++++++++++++ .../src/python/gnuradio/blksimpl/gmsk2.py | 159 -------- .../src/python/gnuradio/blksimpl/gmsk2_pkt.py | 174 --------- gnuradio-core/src/python/gnuradio/blksimpl/pkt.py | 4 +- gnuradio-core/src/python/gnuradio/blksimpl/psk.py | 67 ++++ gnuradio-core/src/python/gnuradio/gr/Makefile.am | 1 + gnuradio-core/src/python/gnuradio/gr/qa_agc.py | 433 +++++++++++++++++++++ .../src/python/gnuradio/modulation_utils.py | 81 ++++ gnuradio-core/src/python/gnuradio/packet_utils.py | 31 +- 13 files changed, 1635 insertions(+), 351 deletions(-) create mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/dbpsk.py create mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/dqpsk.py create mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/gmsk.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/gmsk2.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/gmsk2_pkt.py create mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/psk.py create mode 100755 gnuradio-core/src/python/gnuradio/gr/qa_agc.py create mode 100644 gnuradio-core/src/python/gnuradio/modulation_utils.py (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/Makefile.am b/gnuradio-core/src/python/gnuradio/Makefile.am index 05e42a737..4f8972f09 100644 --- a/gnuradio-core/src/python/gnuradio/Makefile.am +++ b/gnuradio-core/src/python/gnuradio/Makefile.am @@ -28,6 +28,7 @@ grpython_PYTHON = \ audio.py \ eng_notation.py \ eng_option.py \ + modulation_utils.py \ packet_utils.py \ gr_unittest.py \ optfir.py \ diff --git a/gnuradio-core/src/python/gnuradio/blksimpl/Makefile.am b/gnuradio-core/src/python/gnuradio/blksimpl/Makefile.am index 184aa7a29..8122bfa6a 100644 --- a/gnuradio-core/src/python/gnuradio/blksimpl/Makefile.am +++ b/gnuradio-core/src/python/gnuradio/blksimpl/Makefile.am @@ -29,14 +29,16 @@ grblkspythondir = $(grpythondir)/blksimpl grblkspython_PYTHON = \ __init__.py \ am_demod.py \ + dbpsk.py \ + dqpsk.py \ filterbank.py \ fm_demod.py \ fm_emph.py \ - gmsk2.py \ - gmsk2_pkt.py \ + gmsk.py \ nbfm_rx.py \ nbfm_tx.py \ pkt.py \ + psk.py \ rational_resampler.py \ standard_squelch.py \ wfm_rcv.py \ diff --git a/gnuradio-core/src/python/gnuradio/blksimpl/dbpsk.py b/gnuradio-core/src/python/gnuradio/blksimpl/dbpsk.py new file mode 100644 index 000000000..20b940bf0 --- /dev/null +++ b/gnuradio-core/src/python/gnuradio/blksimpl/dbpsk.py @@ -0,0 +1,370 @@ +# +# Copyright 2005,2006 Free Software Foundation, Inc. +# +# This file is part of GNU Radio +# +# GNU Radio is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. +# +# GNU Radio is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

These changes (1) fix a problem with gr_feval* where when called from a live flowgraph, they resulted in the call back into Python occuring without holding the Global Interpreter Lock causing a SIGSEGV. (2) add gr_bin_statistics_f which combines statistics gathering with a control state machine that allows spectrum sensing or related applications that need to step through the spectrum to be built. (3) usrp_spectrum_sense.py which ties all this together in an application which steps through the spectrum a chunk at a time and gathers statistics. In the current version, the stats are gathered by nothing is done with them. Think of this as the framework for a real application. This code may require tuning of the --tune-delay and --dwell-delay timeouts to ensure that the samples being processed are associated with the given center frequency. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@3907 221aa14e-8319-0410-a670-987f0aec2ac5 --- gnuradio-core/src/python/gnuradio/gr/Makefile.am | 1 + .../src/python/gnuradio/gr/qa_bin_statistics.py | 226 +++++++++++++++++++++ 2 files changed, 227 insertions(+) create mode 100755 gnuradio-core/src/python/gnuradio/gr/qa_bin_statistics.py (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/gr/Makefile.am b/gnuradio-core/src/python/gnuradio/gr/Makefile.am index ec91917b2..fcf026146 100644 --- a/gnuradio-core/src/python/gnuradio/gr/Makefile.am +++ b/gnuradio-core/src/python/gnuradio/gr/Makefile.am @@ -48,6 +48,7 @@ noinst_PYTHON = \ qa_add_v_and_friends.py \ qa_agc.py \ qa_basic_flow_graph.py \ + qa_bin_statistics.py \ qa_cma_equalizer.py \ qa_complex_to_xxx.py \ qa_constellation_decoder_cb.py \ diff --git a/gnuradio-core/src/python/gnuradio/gr/qa_bin_statistics.py b/gnuradio-core/src/python/gnuradio/gr/qa_bin_statistics.py new file mode 100755 index 000000000..75cfc8308 --- /dev/null +++ b/gnuradio-core/src/python/gnuradio/gr/qa_bin_statistics.py @@ -0,0 +1,226 @@ +#!/usr/bin/env python +# +# Copyright 2006 Free Software Foundation, Inc. +# +# This file is part of GNU Radio +# +# GNU Radio is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. +# +# GNU Radio is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

9967e2e7664dbc96a5d1587c194cc648d01cf487 Mon Sep 17 00:00:00 2001 From: trondeau Date: Sat, 4 Aug 2007 15:21:34 +0000 Subject: merged -r5966:6112 on trondeau/ofdm_mod. Allows for generic constellations (supports bpsk, qpsk, 8psk, qam16, qam64, and qam256 currently), fixes some bugs in the correlation and altered default parameters for over-the-air operation. This merge fixes ticket:156 and ticket:157. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@6113 221aa14e-8319-0410-a670-987f0aec2ac5 --- gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py | 51 +++++++++++++++------- gnuradio-core/src/python/gnuradio/blksimpl/psk.py | 6 +++ gnuradio-core/src/python/gnuradio/gruimpl/crc.py | 4 +- 3 files changed, 44 insertions(+), 17 deletions(-) (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py b/gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py index d4fef81ec..b040d8c7f 100644 --- a/gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py +++ b/gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py @@ -24,6 +24,7 @@ import math from numpy import fft from gnuradio import gr, ofdm_packet_utils import gnuradio.gr.gr_threading as _threading +import psk, qam from gnuradio.blksimpl.ofdm_receiver import ofdm_receiver @@ -81,15 +82,21 @@ class ofdm_mod(gr.hier_block): padded_preambles.append(padded) symbol_length = options.fft_length + options.cp_length -

Also adds/updates Python plotting tools and a branchless clip algorithm in gr_math.h. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@7324 221aa14e-8319-0410-a670-987f0aec2ac5 --- .../src/python/gnuradio/blks2impl/Makefile.am | 6 + .../src/python/gnuradio/blks2impl/ofdm.py | 311 +++++++++++++++++++++ .../src/python/gnuradio/blks2impl/ofdm_receiver.py | 112 ++++++++ .../python/gnuradio/blks2impl/ofdm_sync_fixed.py | 49 ++++ .../src/python/gnuradio/blks2impl/ofdm_sync_ml.py | 142 ++++++++++ .../src/python/gnuradio/blks2impl/ofdm_sync_pn.py | 146 ++++++++++ .../python/gnuradio/blks2impl/ofdm_sync_pnac.py | 131 +++++++++ .../src/python/gnuradio/blksimpl/Makefile.am | 6 - gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py | 305 -------------------- .../src/python/gnuradio/blksimpl/ofdm_receiver.py | 64 ----- .../python/gnuradio/blksimpl/ofdm_sync_fixed.py | 41 --- .../src/python/gnuradio/blksimpl/ofdm_sync_ml.py | 135 --------- .../src/python/gnuradio/blksimpl/ofdm_sync_pn.py | 135 --------- .../src/python/gnuradio/blksimpl/ofdm_sync_pnac.py | 126 --------- 14 files changed, 897 insertions(+), 812 deletions(-) create mode 100644 gnuradio-core/src/python/gnuradio/blks2impl/ofdm.py create mode 100644 gnuradio-core/src/python/gnuradio/blks2impl/ofdm_receiver.py create mode 100644 gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_fixed.py create mode 100644 gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py create mode 100644 gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_pn.py create mode 100644 gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_pnac.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/ofdm.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/ofdm_receiver.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/ofdm_sync_fixed.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/ofdm_sync_ml.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/ofdm_sync_pn.py delete mode 100644 gnuradio-core/src/python/gnuradio/blksimpl/ofdm_sync_pnac.py (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/blks2impl/Makefile.am b/gnuradio-core/src/python/gnuradio/blks2impl/Makefile.am index e3d83aeee..934326d8f 100644 --- a/gnuradio-core/src/python/gnuradio/blks2impl/Makefile.am +++ b/gnuradio-core/src/python/gnuradio/blks2impl/Makefile.am @@ -40,6 +40,12 @@ grblkspython_PYTHON = \ cpm.py \ nbfm_rx.py \ nbfm_tx.py \ + ofdm.py \ + ofdm_receiver.py \ + ofdm_sync_fixed.py \ + ofdm_sync_pn.py \ + ofdm_sync_pnac.py \ + ofdm_sync_ml.py \ pkt.py \ psk.py \ qam.py \ diff --git a/gnuradio-core/src/python/gnuradio/blks2impl/ofdm.py b/gnuradio-core/src/python/gnuradio/blks2impl/ofdm.py new file mode 100644 index 000000000..491ef1a19 --- /dev/null +++ b/gnuradio-core/src/python/gnuradio/blks2impl/ofdm.py @@ -0,0 +1,311 @@ +#!/usr/bin/env python +# +# Copyright 2006,2007 Free Software Foundation, Inc. +# +# This file is part of GNU Radio +# +# GNU Radio is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3, or (at your option) +# any later version. +# +# GNU Radio is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Instead of using the CP timing signal, it correlates against the known preamble just to send along the timing trigger. This works nicely and keeps the frequency more constant in the receiver since it updates the estimate every received symbol. Read the comments inside to see why it's 'mostly fixed' -- this was mostly proving a point for myself today. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8199 221aa14e-8319-0410-a670-987f0aec2ac5 --- .../src/python/gnuradio/blks2impl/ofdm_sync_ml.py | 59 +++++++++++++--------- 1 file changed, 34 insertions(+), 25 deletions(-) (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py b/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py index a93852623..59c4913d1 100644 --- a/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py +++ b/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py @@ -1,6 +1,6 @@ #!/usr/bin/env python # -# Copyright 2007 Free Software Foundation, Inc. +# Copyright 2007,2008 Free Software Foundation, Inc. # # This file is part of GNU Radio # @@ -24,21 +24,16 @@ import math from gnuradio import gr class ofdm_sync_ml(gr.hier_block2): - def __init__(self, fft_length, cp_length, snr, logging): + def __init__(self, fft_length, cp_length, snr, kstime, logging): ''' Maximum Likelihood OFDM synchronizer: J. van de Beek, M.

Adds convolutional encoder and decoder corresponding to the R=1/2, K=7 CCSDS standard ("Voyager"). This code is a GNU Radio wrapper around a 1995-era KA9Q portable-C implementation, and is designed for continuous streaming data, not packets. The encoder takes MSB packed bytes and outputs channel symbols 0 or 1. The decoder uses soft-decision Viterbi decoding on a floating point stream of (possibly noise corrupted) [1.0, 1.0] symbols, and outputs MSB packed decoded bytes. Benchmarking on a 2.16 GHz Intel Core 2 Duo shows 4.7 Mbps decoding rate at 100% CPU usage (single core). (There is a newer KA9Q library that implements SIMD speed ups with correspondingly faster performance.) The KA9Q library is placed into src/lib/viterbi.

It uses the energy calculation to normalize the correlation and the timing sequence and correlation together to determine the timing. This works for frequencies of +-0.6 offset, which is a limiting factor still in the performance but better than the previous checkin. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8222 221aa14e-8319-0410-a670-987f0aec2ac5 --- .../src/python/gnuradio/blks2impl/ofdm_sync_ml.py | 36 +++++++++++++++------- 1 file changed, 25 insertions(+), 11 deletions(-) (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py b/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py index 59c4913d1..7c75d7f1d 100644 --- a/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py +++ b/gnuradio-core/src/python/gnuradio/blks2impl/ofdm_sync_ml.py @@ -98,7 +98,7 @@ class ofdm_sync_ml(gr.hier_block2): self.connect(self.diff, self.pk_detect) # The DPLL corrects for timing differences between CP correlations - use_dpll = 1 + use_dpll = 0 if use_dpll: self.dpll = gr.dpll_bb(float(symbol_length),0.01) self.connect(self.pk_detect, self.dpll) @@ -117,21 +117,29 @@ class ofdm_sync_ml(gr.hier_block2): kstime.reverse() self.kscorr = gr.fir_filter_ccc(1, kstime) self.corrmag = gr.complex_to_mag_squared() + self.div = gr.divide_ff() # The output signature of the correlation has a few spikes because the rest of the # system uses the repeated preamble symbol.

(2) Don't permanently change PATH in config/sdl.m4 (to prevent real problems in MinGW and potential problems for any code that runs after sdl.m4 and depends on PATH). git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8316 221aa14e-8319-0410-a670-987f0aec2ac5 --- gnuradio-core/src/python/gnuradio/gr/qa_wavefile.py | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/gr/qa_wavefile.py b/gnuradio-core/src/python/gnuradio/gr/qa_wavefile.py index c6d376a81..3ba5dfbce 100755 --- a/gnuradio-core/src/python/gnuradio/gr/qa_wavefile.py +++ b/gnuradio-core/src/python/gnuradio/gr/qa_wavefile.py @@ -57,8 +57,9 @@ class qa_wavefile(gr_unittest.TestCase): in_f = file(infile, 'rb') out_f = file(outfile, 'rb') - in_data = in_f.read(getsize(infile)) - out_data = out_f.read(getsize(outfile)) + in_data = in_f.read() + out_data = out_f.read() + out_f.close() os.remove(outfile) self.assertEqual(in_data, out_data) -- cgit From 3da84a4ac3147828700ed4e26f4d007d1a362063 Mon Sep 17 00:00:00 2001 From: jcorgan Date: Mon, 19 May 2008 02:36:00 +0000 Subject: Fix breakage introduced in r6228 (Josh Blum) git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8441 221aa14e-8319-0410-a670-987f0aec2ac5 --- gnuradio-core/src/python/gnuradio/blks2impl/channel_model.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/blks2impl/channel_model.py b/gnuradio-core/src/python/gnuradio/blks2impl/channel_model.py index 2e2ac6e27..7d53dd921 100644 --- a/gnuradio-core/src/python/gnuradio/blks2impl/channel_model.py +++ b/gnuradio-core/src/python/gnuradio/blks2impl/channel_model.py @@ -52,11 +52,11 @@ class channel_model(gr.hier_block2): self.connect(self.noise_adder, self) - def set_noise_voltage(noise_voltage): + def set_noise_voltage(self, noise_voltage): self.noise.set_amplitude(noise_voltage) - def set_frequency_offset(frequency_offset): + def set_frequency_offset(self, frequency_offset): self.freq_offset.set_frequency(frequency_offset) - def set_taps(taps): + def set_taps(self, taps): self.multipath.set_taps(taps) -- cgit From fcf2cfb0c0949db3cb7cdd635376a683cbc13f4d Mon Sep 17 00:00:00 2001 From: eb Date: Mon, 26 May 2008 13:30:41 +0000 Subject: channel_model.py now allows to set the random seed for the noise source via __init__ and adds a function to set the timing offset.

Adds --enable-python option to configure (defaults to yes). Using --disable-python or --enable-python=no will cause only C++ API targets to be created and installed. Several new shared libraries are now created. Where in the past, the C++ objects of the actual gnuradio blocks that were in a component were hidden inside their corresponding Python extension modules, these are now split out into a libgnuradio-foo.so library, and the _foo.so Python module is linked to that. This has been the way several top- level components have operated for some time, such as gr-audio-alsa and gr-usrp and gr-usrp2. This changeset applies that pattern to all components. C++ API users can use pkg-config to discover the cflags and libs parameters needed to include and link against these libraries. These components have not been tested: gr-comedi gr-audio-osx gr-audio-windows Passes distcheck. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11150 221aa14e-8319-0410-a670-987f0aec2ac5 --- gnuradio-core/src/python/gnuradio/Makefile.am | 2 ++ 1 file changed, 2 insertions(+) (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/Makefile.am b/gnuradio-core/src/python/gnuradio/Makefile.am index 5cc0824b3..ed36bbae7 100644 --- a/gnuradio-core/src/python/gnuradio/Makefile.am +++ b/gnuradio-core/src/python/gnuradio/Makefile.am @@ -21,6 +21,7 @@ include $(top_srcdir)/Makefile.common +if PYTHON SUBDIRS = gr gru gruimpl blks2 blks2impl vocoder grpython_PYTHON = \ @@ -34,3 +35,4 @@ grpython_PYTHON = \ gr_unittest.py \ optfir.py \ window.py +endif -- cgit From e573f752e6d9366a2629789a7158cce645a44235 Mon Sep 17 00:00:00 2001 From: jcorgan Date: Thu, 9 Jul 2009 16:45:11 +0000 Subject: Adds generic msgq runner convenience class. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11398 221aa14e-8319-0410-a670-987f0aec2ac5 --- .../src/python/gnuradio/gruimpl/Makefile.am | 1 + .../src/python/gnuradio/gruimpl/msgq_runner.py | 82 ++++++++++++++++++++++ 2 files changed, 83 insertions(+) create mode 100644 gnuradio-core/src/python/gnuradio/gruimpl/msgq_runner.py (limited to 'gnuradio-core/src/python') diff --git a/gnuradio-core/src/python/gnuradio/gruimpl/Makefile.am b/gnuradio-core/src/python/gnuradio/gruimpl/Makefile.am index 314358a7f..ffae4b809 100644 --- a/gnuradio-core/src/python/gnuradio/gruimpl/Makefile.am +++ b/gnuradio-core/src/python/gnuradio/gruimpl/Makefile.am @@ -32,6 +32,7 @@ grupython_PYTHON = \ listmisc.py \ mathmisc.py \ lmx2306.py \ + msgq_runner.py \ os_read_exactly.py \ sdr_1000.py \ seq_with_cursor.py \ diff --git a/gnuradio-core/src/python/gnuradio/gruimpl/msgq_runner.py b/gnuradio-core/src/python/gnuradio/gruimpl/msgq_runner.py new file mode 100644 index 000000000..767a74a71 --- /dev/null +++ b/gnuradio-core/src/python/gnuradio/gruimpl/msgq_runner.py @@ -0,0 +1,82 @@ +# +# Copyright 2009 Free Software Foundation, Inc. +# +# This file is part of GNU Radio +# +# GNU Radio is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3, or (at your option) +# any later version. +# +# GNU Radio is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
