* Trial fix for ticket:258 / integer overflow undefined / phaseeb2008-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | 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
