2008-06-19Merged eb/gcell-wip -r8559:8571 into trunk. The shared queueeb
structure is slightly modified, and the spu dequeue has been streamlined. In addition, the spu Lost-Lock Line Reservation event is now work correctly, though it is still disabled because it's slower than the expontial backoff alternative. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8618 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
2008-05-04Merged eb/gcell-wip -r8302:8307 into trunk. This changeset includeseb
an example of SPE assembler (memset.S), a new file of macros for use with SPE assembler (gc_spu_macs.h), and an extended QA framework. The easy to use QA framework adds support for SPE utility code that's usually not called from the PPE, such as memset. See qa_gcell_general.{h,cc} and qa_memset.c for example usage. memset achieves 44GB/s on the SPE. That's within 3% of ideal. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8308 221aa14e-8319-0410-a670-987f0aec2ac5
2008-04-30Fixed completely buggy memcopy that overwrote potentially lots of memory ineb
atsc_depad.cc. The problem has to do with confusion between input and output sizes, as well as some very wrong pointer math (Dan Halperin). git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8298 221aa14e-8319-0410-a670-987f0aec2ac5

flowgraph reconfiguration bug reported by Tim O'Shea and Mark Schneider. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8271 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
