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
2008-08-23Fix for ticket:214, gr_rotate speedup. We now normalize once everyeb
512 cycles. We also now compute the return value based on the preincremented phase value, thus shortening the dependency chain. This does put the computed result 1 tick ahead of the previous version of the code, but none of the code in the tree depends on the absolute phase. If yours does, sorry. You can work around it by initializing the phase to conj(gr_expj(phase_incr)) instead of gr_complex(1,0). Added QA code to ensure I didn't break anything. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9384 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

2008-04-18Improved 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
