Staircase code decoding method and staircase code decoding apparatus
Provided are a staircase code decoding method and a staircase code decoding apparatus. The method includes: step 1, 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 2, 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 3, sliding the sliding window forwards by a length of N subcode blocks; step 4, 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 5, sliding the sliding window backwards by S.
