Description and Features
The DVB-S2-LDPC-BCH block is a powerful FEC (Forward Error Correction) subsystem for Digital Video Broadcasting via Satellite. In Digital video broadcasting for digital transmission for satellite applications, a powerful FEC sub-system is needed. FEC is based on inner LDPC (Low-Density Parity Check) codes concatenated with outer BCH (Bose ChaudhuriHocquenghem) codes, allowing Quasi Error Free operation close to the Shannon limit.
Features
-
Irregular parity check matrix
-
