2011-07-04gnuradio-examples, gr-audio: moved audio Python and C++ examples into gr-audioJohnathan Corgan
This begins a transition of examples from a separate gnuradio-examples component into an examples directory with the component they go with. In this commit: gnuradio-examples/c++/audio/ => gr-audio/examples/c++ gnuradio-examples/python/audio => gr-audio/examples/python The system installation directory remains $PREFIX/share/gnuradio/examples/audio

2009-10-12Merge branch 'sync' of git@gnuradio.org:trondeau into masterJohnathan Corgan
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 GRC PAM timing example and adding ability to do M-ary PAM. Cleaning up constructor. Moving filter number decision to start work function. ...

2009-08-12Merging trondeau/pfb r11249:11581 into trunk. This adds a few polyphase ↵trondeau
filterbank implementations that do (integer) decimation, (integer) interpolation, arbitrary resampling, and channelizing. gnuradio-example/python/pfb includes a number of different examples of how to use these blocks. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11583 221aa14e-8319-0410-a670-987f0aec2ac5
2009-01-27Removed DECT Python example. Refer to DECT project in CGRAN for a more ↵jcorgan
comprehensive example. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@10313 221aa14e-8319-0410-a670-987f0aec2ac5
2008-10-27Adds usrp2 example directory, WFM receiver. Default audio rate works out to ↵jcorgan
32015 Hz, which is close enough, but for ALSA, you can use -O plughw:0,0 to get rid of the warning message. A resampler would be ideal. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9863 221aa14e-8319-0410-a670-987f0aec2ac5
2008-09-13Merged r9564:9568 from jcorgan/bert into trunk. Adds BPSK bit error testing ↵jcorgan
examples and support blocks. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9569 221aa14e-8319-0410-a670-987f0aec2ac5
2008-08-19Merged features/mp-sched -r8915:9335 into the trunk. The trunk noweb
contains the SMP aware scheduler. This changeset introduces a dependency on boost 1.35 or later. See source:gnuradio/trunk/README.building-boost for additional info. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9336 221aa14e-8319-0410-a670-987f0aec2ac5

2008-02-08Merged r7478:7608 from michaelld/t186 into trunk. Adds ability to compile ↵jcorgan
GNU Radio modules individually, using already installed dependent libraries and include files. New functionality is enabled using --with-* on configure command line; existing build options should remain unchanged. Nice work by Michael Dickens, still needs documentation update on wiki. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@7617 221aa14e-8319-0410-a670-987f0aec2ac5

* Final gr.top_block and gr.hier_block2 implementation inside gnuradio-core/src/lib/runtime * Implementation of gr.hier_block2 versions of all the old-style blocks in blks. These live in blks2. * Addition of gr.hier_block2 based versions of gr-wxgui blocks * Conversion of all the example code in gnuradio-examples to use this new code * Conversion of all the gr-utils scripts to use the new code The OFDM examples and related hierarchical blocks have not yet been converted. Code in the rest of the tree that is outside the core and example components has also not yet been converted. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@6466 221aa14e-8319-0410-a670-987f0aec2ac5
2007-09-04Merged r6271:6278 from jcorgan/t182 into trunk. Implements ticket:182.jcorgan
Created new top-level component, gr-utils, to hold commonly used utility scripts (originally in gnuradio-examples). These now install into the system path, allowing their use from wherever. Reorganization of gnuradio-examples component: * Commonly used utility scripts moved from python/usrp into gr-utils. * Examples now install into $(prefix)/share/gnuradio/examples/... * Channel coding examples moved into gr-trellis/src/examples, now install from there, only if gr-atsc itself is going to built and installed. * ATSC example scripts now install into example hierarchy * Cruft has been moved into 'limbo' in repository, do not get installed Trunk passes 'make distcheck'. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@6279 221aa14e-8319-0410-a670-987f0aec2ac5
2007-08-27Merged r6171:6186 from jcorgan/fg into trunk.jcorgan
Changes hierarchical flow graph API to use gr.top_block instead of gr.runtime. See discuss-gnuradio mailing list for explanation of changes. GRC has not been updated to use the changed API. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@6187 221aa14e-8319-0410-a670-987f0aec2ac5

2006-09-27Merged changes from eb/digital-wip into trunk.eb
This includes: * renaming gnuradio-examples/python/gmsk2 to gnuradio-examples/python/digital * refactoring the digital data tx and rx test code into benchmark_tx and benchmark_rx. These accept a -m <modulation> argument. <modulation> can currently be selected from gmsk, dbpsk, dqpsk * Two new AGC blocks: gr_agc2: separate attack and delay rates; gr_feedforward_agc: FIR-ish compressor. 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
