2008-08-24Fix compiler warnings across the tree. Adds --enable-warnings-as-errors ↵jcorgan
configure option. Currently compiles with no warnings with GCC 4.2.3 on Ubuntu 8.04. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9396 221aa14e-8319-0410-a670-987f0aec2ac5

2008-08-15Trial fix for ticket:258 / integer overflow undefined / phaseeb
accumulator. Thanks to Stefan Bruens and Philip Ballister for working on this. According to the fine print in the C and C++ standards, if a signed integer type overflows, the result is undefined. As of gcc 4.3, gcc was proving that our code was overflowing, and took advantage of the "undefined" result to short circuit the evaluation. Moral of the story: if you're using a fixed point phase accumulator, or anything else where you're counting on overflow happening, be sure that your variable is unsigned.

2008-07-09Merged jcorgan/ptrfix -r8827:8843 into the trunk.eb
Fix that allows C++ classes derived from gr_hier_block2 to use the new self() method to get a magic object that can be passed to connect or disconnect to refer to their own inputs and outputs. Note that the constructor wrapper of all classes derived from gr_hier_block2 (and thus gr_top_block too) MUST USE the new gnuradio::get_initial_sptr function to get the initial shared pointer. gnuradio::get_initial_sptr works on all block types, and should be used in all new code. See qa_gr_hier_block2_derived.{h,cc} for an example. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8844 221aa14e-8319-0410-a670-987f0aec2ac5
2008-06-10Applied patch from Dean Armstrong to fix gr_repeat (ticket:246). eb
The QA code was not updated to detect the bug and should still be sorted out. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8568 221aa14e-8319-0410-a670-987f0aec2ac5

Radio interface to the Cell Broadband Engine. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8244 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

2008-03-31merging branch trondeau/ofdm r7971:8143. Fixing subcarriers and other issues ↵trondeau
to improve OFDM system operation. Not much more we can do with this than add channel coding and cleaning up. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8144 221aa14e-8319-0410-a670-987f0aec2ac5
2008-03-17Don't define RANDOM_MAX on systems that have already defined it. (Atgdt
present, only NetBSD-current is known to do this.) Improve the comment explaining the situation. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8034 221aa14e-8319-0410-a670-987f0aec2ac5
2008-02-26merged -r7836:7846 from trondeau/ofdmtiming to trunk. This fixes the big ↵trondeau
issues in transmitting OFDM over the air with 1 preamble symbol. Still some smaller issues left. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@7848 221aa14e-8319-0410-a670-987f0aec2ac5

2008-02-21Merged build_config branch into trunk:michaelld
1) Modified top-level run_tests.sh script: a) to execute code for setting or changing the library search path in Darwin (DYLD_LIBRARY_PATH) or Windows (PATH) on those host OSs only, not on other host OSs. b) Added local (to the component making check) library paths to those same search paths, since libtool doesn't do it (unlike in Linux). 2) In all AM Makefiles -except those dealing with USRP firmware-, changes INCLUDES to AM_CPPFLAGS since the former is deprecated. 3) Changed AM_CPPFLAGS to FW_INCLUDES for commands .c.rel in USRP firmware. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@7769 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
2008-02-06Merging trondeau/ofdmfix into branch at -r7582:7586. This allows for ↵trondeau
over-the-air OFDM. Works with all modulations and tested both send and receive on different computers/USRPs. Misses a few packets, so it's not perfect. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@7587 221aa14e-8319-0410-a670-987f0aec2ac5

2008-01-02Merging ofdm2 branch -r7047:7321 into trunk. This updates the OFDM code to ↵trondeau
hier_block2 in blks2impl and removed from blksimpl. The new code implements a decision feedback sync loop to lock the phase/freq, removes two unnecessary premables and performs frame sync and equalization off single preamble symbol. 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
