Error correction encoding method, error correction decoding method, an error correction encoding apparatus, and an error correction decoder

摘要

PROBLEM TO BE SOLVED: To improve processing throughput, and to enhance error correction capability.;SOLUTION: A device for encoding of error correcting codes includes: an outer encoding circuit 33 for performing encoding processing for an outer code; and an inner encoding circuit 34 for performing encoding processing for an inner code, and further includes an inner-encoding input circuit 54 for performing interleaving processing in which a parallel input sequence is sorted into specific lanes, and a specific barrel shift is performed for each inner frame. By carrying out interleaving in which the parallel input sequence is sorted into the specific lanes, and the specific barrel shift is performed for each inner frame, allocation of an information sequence area and a parity sequence area is uniformized, to improve processing throughput and enhance error correction capability.;COPYRIGHT: (C)2011,JPO&INPIT
