H03M0013010000 Coding theory basic assumptions; Coding bounds; Error probability evaluation methods; Channel models; Simulation or testing of codes 1
H03M0013030000 Error detection or forward error correction by redundancy in data representation, i.e. code words containing more digits than the source words 1
H03M0013050000 using block codes, i.e. a predetermined number of check bits joined to a predetermined number of information bits 1
H03M0013070000 Arithmetic codes 1
H03M0013090000 Error detection only, e.g. using cyclic redundancy check [CRC] codes or single parity bit 1
H03M0013110000 using multiple parity bits 1
H03M0013130000 Linear codes 1
H03M0013150000 Cyclic codes, i.e. cyclic shifts of codewords produce other codewords, e.g. codes defined by a generator polynomial, Bose-Chaudhuri-Hocquenghem [BCH] codes (H03M0013170000 takes precedence);; 1
H03M0013170000 Burst error correction, e.g. error trapping, Fire codes 1
H03M0013190000 Single error correction without using particular properties of the cyclic codes, e.g. Hamming codes, extended or generalised Hamming codes 1
H03M0013210000 Non-linear codes, e.g. m-bit data word to n-bit code word [mBnB] conversion with error detection or error correction 1
H03M0013230000 using convolutional codes, e.g. unit memory codes 1
H03M0013250000 Error detection or forward error correction by signal space coding, i.e. adding redundancy in the signal constellation, e.g. Trellis Coded Modulation [TCM] 1
H03M0013270000 using interleaving techniques 1
H03M0013290000 combining two or more codes or code structures, e.g. product codes, generalised product codes, concatenated codes, inner and outer codes 1
