Adding new example script for using the new PFB arbitrary resampler interface. One resampler takes user-generated taps and another resampler just takes the resampling rate. Both input and output signals are plotted.
Modifying blsk2 wrapper for PFB arbitrary resampler to allow the user to just specify the requested resampling rate without providing their own filter taps.
uhd: reverting tag changes on uhd single usrp source, there seems to be issues with the work() logic
uhd: removed default value chan=0 in the cc files
WITH_INCLUDES _must_ be last
uhd: replaced CFLAGS with CPPFLAGS variable, and fixed swig args FIXME
uhd: default channel params to zero for single source and sink blocks
Revert "Removed usrp2-firmware from being automatically built."
Remove generated file from repo
Removed usrp2-firmware from being automatically built.
uhd: added libdir to UHD CFLAGS (shared by lib and swig)
Swapping out preset keys until I work out some of their issues.
Modifying QA tests for the sample tags. By default, it only checks the sizes of the tags since order is not specified or guarenteed.
Block is a gr_block, so this sets its relative rate. Was required for using in the QA of the sample tags code.
Removing global pmt constants. Were causing segfaults during make check. Must fix this later.
Fixing up the UHD sample tag example to take command line options.
Swapping order of testing rrate.
Changing propagation policy enum type name and making a few other minor edits.
Changing API for gr_skiphead to use uint64_t for the offset instead of size_t (still unsigned). Fixes issue #304.
Adding typedef for uint64_t and int64_t so we can use them through SWIG.
...
Passes make distcheck.

just specify the requested resampling rate without providing their own filter taps.
Taps are then generated inside hier_block2 to cover full bandwidth of input signal.
Optional attenuation parameter may be provided.

Move all occurrences of swig_built_sources out of Makefile.am's.
Move all SWIG related use of BUILT_SOURCES out of Makefile.am's.
Clean up 'if PYTHON' conditionalization in gr-*
Still left to do: fix Makefile.swig CLEANFILES and no_dist_files
such that they remove exactly the generated files.

Rename {dis,}connect to {dis,}primitive_connect in .i file.
Update python code to reflect change.

and to_top_block.
basic_block was renamed because the number of guile generic methods on
basic_block was getting large and confusing. to_hier_block2 and
to_top_block were added to support coercion to those types in guile
(and python). This change simplifies the handling of "connect" in guile.

Ignores it if directory is now writable.

Also fixed gr_unittest.py to print to the screen and fail make check properly if there's an error.
Need to find a way to use XML runner with main() to fail make check and output to screen, too.
|
|
|
|
gr_unittest.py was updated to handle the path and file creation and run the XML runner
gr_xmlrunner.py is a public domain program written by Sebastian Rittau <srittau@jroger.in-berlin.de> (THANKS!) to extend Python's unittest module to handle XML JUnit format output. This was renamed from xmlrunner.py if any future work is done on it from our project as well as to keep the namespace clean and clear.
qa_skiphead.py is a first test program for the XML output. Creates an outputfile $HOME/.gnuradio/unittest/python/test_skiphead.xml.

* gnuradio/wip/udp_source_sink:
gnuradio-core: update copyrights
gnuradio-core: allow swig to handle exceptions in UDP source/sink
grc: update UDP source and sink block wrappers
Simplify USE_SELECT usage
Return immediately when using d_residual.
Defend against a peer that sends an invalid message length.
Move initialization of select timeout
Correct update of d_temp_offset (parallel construction)
Identify memory leaks that occur on error conditions
Use -1 as file descriptor "not open" value instead of 0
Add additional conditionalization of networking includes
Flush pending errors in gr_udp_sink on disconnect()
Rework UDP source and sink, with incompatible API changes
Updates to udp source/sink (select(), wait, cleanup)
Discard data in gr_udp_sink until receiver is started.
Use getaddrinfo in gr_udp_{source,sink}
Changes to gr_udp_{source,sink} for MinGW
Ignore ENOPROTOOPT return from setsockopt(SO_LINGER)

|
Remove source address specifications for sink; add connect() and
disconnect() to sink; add get_port() to source; add optional EOF
signaling (using zero-length packets) to sink and source; modify
dial_tone, vector, and audio examples to match new code; add qa
test case.

produces the correct output for oversampling_rate = 1.

This block performs scrambling by XORing the input sequence with
the output of an LFSR. Repeating this operation restores the original
sequence.
(This differs from gr.scrambler_bb(), which convolves the input sequence
with the LFSR output.)
The additive scrambler allows an optional bit count after which the LFSR
is reset to its initial seed. This allows use with, e.g., packetized
fixed length payloads.

with the PFB clock recovery in the demod block allows arbitrary real numbers for the number of samples per symbol. We will have to chance the transmit and recieve path code in the examples to take advantage of this.

This merge adds polyphase clock recovery, implements new PAM demodulators
that use it, and also moves GRC examples to gnuradio-examples component.
See merge commit diff for updated files post merge.
* 'sync' of git@gnuradio.org:trondeau: (54 commits)
Reverting dqpsk to be mpsk_receiver based and not change its behavior.
Fixing initialization of timing gains. Alpha should be < 1, and beta should be << 1.
This splits the rate into a fractional an integer value, which allows the loop to adjust the fractional rate while the integer rate keeps the increments moving properly. Allows the max rate deviation to be independent of the integer rate. Scaling of the differential taps also allows alpha and beta to operate independent of the rate when fractional samples per symbol are used. Slightly more tolerant to large signal values, but they still should be close to +/-1.
Fixing compiler warnings.
Adding dqpsk2 block to makefile for installation.
Adding DQPSK version that uses the PFB timing sync block (dqpsk2).
Minor fixes for logging.
Fixing import of UI file.
Temporary working dbpsk2 example until we match everything.
Working DBPSK implementation with new PFB clock recovery block. The feedforward AGC wasn't playing nicely, the frequency aquistion range was increased to swing half the sample rate in either direction, and the number of filter phases to use was increased to 32.
A bit of code cleanup.
Starting to rework QT app to control new PFB clock recovery alg.
Making old dbpsk work again to compare against new version.
Adding new DBPSK block with new PFB clock recovery alg.
Revert "More additions to PAM timing simulation."
More additions to PAM timing simulation.
Using 2-PAM by default.

Cleaning up constructor.
Moving filter number decision to start work function.
