The author of gr-dvbt looked at this issue when he developed the
DVB-T receiver. Here's a blog entry on his findings. http://yo3iiu.ro/blog/?p=1393 He benchmarked the IT++ decoder in last place. IT++ = 2-3 Mbps gr-trellis = 5 Mbps Karn C = 7-8 Mbps gr-dvbt = 39-40 Mbps The gr-dvbt receiver is now part of GNU Radio as of the last release, 3.7.8. The SSE2 viterbi decoder module is here: https://github.com/gnuradio/gnuradio/blob/master/gr-dtv/lib/dvbt/dvbt_viterbi_decoder_impl.cc In addition, I believe there's another decoder in gr-fec. I'm not very familiar with it, so maybe someone else can comment on it. Looks like it's in this module: https://github.com/gnuradio/gnuradio/blob/master/gr-fec/lib/cc_decoder_impl.cc Ron On 09/15/2015 12:47 AM, Jeon wrote:
