gr-dvbs2rx

Out-of-tree GNU Radio module available in GNU Radio World

gr-dvbs2rx supplies the bit-interleaved coded-modulation decoding stages used by DVB-S2 and DVB-T2 receivers. Its blocks convert soft constellation decisions into deinterleaved codewords, perform low-density parity-check decoding, and apply the outer BCH correction needed to recover protected payload bits. The module is designed as the forward-error-correction core of a larger receiver rather than a complete tuner and synchronization chain, and it supports the standard frame structures and code configurations used by those broadcast systems.
