H03M13/1194 - CPC Classification

Classification description:

Coding, decoding or code conversion, for error detection or error correction; Coding theory basic assumptions; Coding bounds; Error probability evaluation methods; Channel models; Simulation or testing of codes; Error detection or forward error correction by redundancy in data representation, i.e. code words containing more digits than the source words using block codes, i.e. a predetermined number of check bits joined to a predetermined number of information bits using multiple parity bits; Codes on graphs and decoding on graphs, e.g. low-density parity check [LDPC] codes; Codes on graphs other than LDPC codes Repeat-accumulate [RA] codes
