Abstract: Systems and methods are provided for implementing list decoding in a Reed-Solomon (RS) error-correction system. A detector can provide a decision-codeword from a channel and can also provide soft-information for the decision-codeword. The soft-information can be organized into an order of combinations of error events for list decoding. An RS decoder can employ a list decoder that uses a pipelined list decoder architecture. The list decoder can include one or more syndrome modification circuits that can compute syndromes in parallel. A long division circuit can include multiple units that operate to compute multiple quotient polynomial coefficients in parallel. The list decoder can employ iterative decoding and a validity test to generate error indicators. The iterative decoding and validity test can use the lower syndromes.

Abstract: The codec includes an encoding/decoding operation module and a basic matrix storage module. In the stored basic matrix Hb, for all girths with length of 4, any column element of i, j, k or l constituting the girths in anti-clockwise or clockwise always satisfies inequality: (i−j+k−1) mod z≠0, wherein z is the extension factor. When generating the basic matrix, firstly the number of rows M, number of columns N, and weight vectors of the rows and columns are determined, an irregularly original basic matrix is constructed; then the position of ‘1’ is filled by a value chosen from set {0, 1, 2, . . . , z−1} to obtain the basic matrix Hb. The basic matrix Hb obtained by storing constitutes the desired encoder/decoder. The encoder/decoder according to the present invention can effectively eliminate error-floor phenomenon of LDPC codes and accelerate the falling speed of BER curve.
