133 Construction Method for LDPC Codes Base on the Joint Row-Column Decoding Algorithm Available to Purchase

The joint row-column decoding algorithm for Low Density Parity Check (LDPC) codes is widely used in high-speed communications. However, the pipeline operation of the decoder may introduce memory access conflicts, which heavily deteriorates the decoding throughput. To essentially deal with the issue of memory access conflicts, we present a construction method of LDPC codes for joint row-column decoding algorithm. It can avoid routing congestion and reduce decoder pipeline delay. The LDPC codes constructed by the proposed method can greatly reduce the decoding iterations. Meanwhile, the performance of them is the same as the codes constructed by conventional Block Progressive Edge-Growth (Block-PEG) algorithm.
