A decoding method and device for Turbo product codes, a decoding device, a decoder and a computer storage medium are provided. The method includes: a received codeword of a Turbo product code is acquired, and iterative decoding is performed on the received codeword for a set first iterative decoding times (S); a decoding result of iterative decoding performed for the first iteration times is judged according to a first decoding rule to obtain a decoding identifier representing the decoding result (S); and error correction processing is performed on the Turbo product code on which iterative decoding is performed for the first iteration times according to the decoding identifier (S).

Decoding method and device for turbo product codes, decoder and computer storage medium

Provided are a staircase code decoding method and a staircase code decoding apparatus. The method includes: step, obtaining the length L of a sliding window, and continuously obtaining, starting from a P-th subcode block, L subcode blocks as first to-be-decoded subcode blocks in the sliding window; step, dividing the first to-be-decoded subcode blocks into a plurality of first to-be-decoded groups, respectively decoding the plurality of to-be-decoded groups to be decoded, and updating the plurality of first to-be-decoded groups according to a decoding result to obtain first updated subcode blocks; step, sliding the sliding window forwards by a length of N subcode blocks; step, dividing second to-be-decoded subcode blocks into a plurality of second to-be-decoded groups, decoding the plurality of second to-be-decoded groups, obtaining second updated subcode blocks, and outputting first M subcode blocks among the second updated subcode blocks; and step, sliding the sliding window backwards by S.
