2009-03-19Fix for ticket:348, Stopping a process does not properly terminate USRP1.eb
This is a partial merge from eb/t348 10637:10648, and contains the actual fix. The next commit will contain the rest of the merge which adds a -N <nsamples> argument to usrp_siggen.py, usrp_siggen.cc and test_usrp_standard_tx.cc. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@10649 221aa14e-8319-0410-a670-987f0aec2ac5
2009-03-14Merged r10554:10595 from michaelld/am_swig_4 into trunk. Major overhaul of ↵jcorgan

2009-02-25Merged mld/fix_makefile_gen -r10446:10509 to trunk. This cleans upeb
the generation of the Makefile.gen's that occurs in gr-trellis, lib/gengen and lib/filter. If you change any code generator such that it generates a different set of generated file names, you must execute "make generate-makefile" in a non-VPATH build to regenerate the Makefile.gen's. Once they are regenerated, commit them to the repo. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@10511 221aa14e-8319-0410-a670-987f0aec2ac5

2008-05-08Applied patches from Don Ward.eb
(1) Close out_f before removing it in gnuradio-core/src/python/gnuradio/gr/qa_wavefile.py (to prevent make check failure). (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
2008-04-22Merged eb/gcell -r8215:8243 into trunk. This adds gr-gcell, the GNUeb
Radio interface to the Cell Broadband Engine. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8244 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-18Improved performance of the ML sync (with added computations). It uses the ↵trondeau
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
2008-04-17Improved the pnac ofdm sync block. This is based on a VTC'99 paper by ↵trondeau
Tufvesson, et al. that does a bit more work than the Schmidl and Cox to produce a more identifiable peak for the timing. This seems to work well in the simulation for low frequency errors. The correlation doesn't seem to track well, though. See the comments for more info. Also, the peak detection requires unity amplitude for the threshold detection. So, who wants to make an OFDM AGC? git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8217 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-16to complete what I started, this makes the ofdm_sync_fixed block work again ↵trondeau
in the OFDM receiver. Its only used for testing in the simulation mode if you want to remove any affects of the synchronization blocks. You have to manually edit the number of symbols and any fractional frequency offset you might want to use. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8213 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-16The ofdm_sync_pnac method now works, though not that well. The frequency ↵trondeau
estimation is horrible and it still has some problems that may be a fundamental issue with the idea. I need to get the paper this was based off of to review it. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8212 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-15Fixed to pass distcheck, except QA test operates differently during ↵jcorgan
distcheck vs. command-line, so commented out for now. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8207 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-15Merged r8195:8205 from jcorgan/ecc into trunk. Adds convolutional encoderjcorgan
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 could use some cleanup, file/function renaming, and refactoring, or even replacement with the newer libfec code that is available. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8206 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-15Mostly fixed the van de Beek ML synchronization scheme. Instead of using the ↵trondeau
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
2008-04-15Adjusting structure a bit to redistribute responsibilities. This does not ↵trondeau
change the behavior or performance at all. The sync. block only calculates the frequency and timing signals and now outputs the fine frequency adjustment signal from output 0 and the timing signal for the start of the packet from output 1. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8198 221aa14e-8319-0410-a670-987f0aec2ac5
