gr-fec GNUradio package contain Viterbi decoder's for weather satellite telemetry decoding

-- fec_decode_viterbi_ahrpt_metop_cb It is rate 3/4 decoder with depuncturing for MetOp AHRPT satellite telemetry decoding

-- fec_decode_viterbi_ahrpt_fengyun_cb It is rate 3/4 decoder with depuncturing for Fengyun3 AHRPT satellite telemetry decoding

-- fec_decode_viterbi_bpsk_fb It is rate 1/2 decoder with no depuncturing for GOES LRIT telemetry decoding

It contain also simple convolutional encoder -- fec_encode_convolutional_27_bb It is 1/2 encoder for real data for transmition or for test purpose of decoders

This package requires that gnuradio-core is already installed and viterbi.c + viterbi.h file in Viterbi folder for new replaced.

It also depends on some GNU Radio prerequisites, such as Boost and cppunit.

To build and install use these commands:

.. cd to gr-fec directory and do next steps

$ ./bootstrap $ ./configure $ make $ make check $ make install $ ldconfig
