Abstract
Methods and apparatuses for parallel decoding and data processing of Turbo codes are provided. The method includes: a codeword dividing step for dividing a whole codeword into Q sub-blocks to form a plurality of boundaries between adjacent sub-blocks of the Q sub-blocks so as to decode the Q sub-blocks, wherein the decoding process comprises P times of decoding iterations, and wherein Q is a positive integer and Q>1 and P is a positive integer and P>1; and a boundary moving step for moving at least one position of the boundaries formed in a pth decoding iteration by an offset Δ before performing a (p+n)th decoding iteration, wherein p is a positive integer and 1≦p
