Hi Bob, Have a look at the manual. The API itself is quite well described I think: http://gnuradio.org/doc/doxygen/page_fec.html It doesn't cover the very recently added TPC and LDPC implementations. http://gnuradio.org/doc/doxygen/classgr_1_1fec_1_1ldpc__decoder.html http://gnuradio.org/doc/doxygen/classgr_1_1fec_1_1ldpc__decoder.html http://gnuradio.org/doc/doxygen/classgr_1_1fec_1_1tpc__encoder.html http://gnuradio.org/doc/doxygen/classgr_1_1fec_1_1tpc__decoder.html Those could use work on their documentation. We're also about to merge in another approach to LDPC encoding and decoding based on Tracie Perez's GSoC work. You can see the wip branch here: https://github.com/trondeau/gnuradio/tree/fec/ldpc_methods And the GSoC presentations: http://www.trondeau.com/grcon2013-presentations#gsoc-perez http://www.trondeau.com/grcon2013-presentations#gsoc-manu Johannes Demel is working on polar codes this summer. What's your particular interest in FEC? Are you looking to use it or implement other codes not already in gr-fec? For the FEC API itself, there is no other reference than the manual page and a presentation from the original author at our GRCons: http://www.trondeau.com/grcon14-presentations#tut-mccarthy http://www.trondeau.com/grcon2013-presentations#tut-mccarthy Tom
