    摘要： Detecting, avoiding and/or correcting problematic puncturing patterns in parity bit streams used when implementing punctured Turbo codes is achieved without having to avoid desirable code rates. This enables identification/avoidance of regions of relatively poor Turbo code performance. Forward error correction comprising Turbo coding and puncturing achieves a smooth functional relationship between any measure of performance and the effective coding rate resulting from combining the lower rate code generated by the Turbo encoder (600) with puncturing of the parity bits. In one embodiment, methods to correct/avoid degradations due to Turbo coding are implemented by puncturing interactions when two or more stages of rate matching (610, 620) are employed.

    摘要： A QCTC (Quasi-Complementary Turbo Code) generating apparatus having: a turbo encoder for generating an information symbol sequence and a plurality of parity symbol sequences by encoding the information symbol sequence; a channel interleaver for individually interleaving the symbol sequences, generating new parity symbol sequences by multiplexing the symbols of parity symbol sequences with the same priority levels, and serially concatenating the information symbol sequence and the new parity symbol sequences; and a QCTC generator for generating a sub-code with a given code rate by recursively selecting a predetermined number of symbols from the concatenated symbol sequence at a given starting position.

    摘要： In a system in which systematic code, comprising information alphabet elements to which parity alphabet elements have been added, is transmitted and received, (1) K0 dummy alphabet elements are added to K information alphabet elements to generate first code of K1 (=K+K0) information alphabet elements; (2) M parity alphabet elements, created from the first code of K1 information alphabet elements, are added to this first code of K1 information alphabet elements, and the K0 dummy alphabet elements are deleted to generate systematic code of N (=K+M) alphabet elements; and (3) the systematic code is received on the receiving side, the K0 dummy alphabet elements are added to the received systematic code, and decoding of the code of N1 alphabet elements obtained by adding the K0 dummy alphabet elements, is performed.
