LDPC Decoder Applications
DVB-C2, the successor of DVB-C, contains a subset of the LDPC codes as defined in DVB-S2. A single code is used (64800 bits, code rate 2/3) that was introduced with DVB-T2 only. Since for cable networks high signal-to-noise ratios are common, the lower code rates have been removed allowing for a reduced decoder complexity. The code with the lowest code rate (16200 bits, code rate 4/9) is only used for the sending of signalling information.
