A New LDPC decoding algorithm
Zongxin Wang
Abstract
Low-density parity-check code (LDPC) with good application foreground has excellent performance.A news LDPC de-coding algorithm,which combined SIHO (soft-input hard-output)list-based decoding with belief propagation(BP) decoding is presen-ted.Comparing with BP and MLD algorithm in performance and complexity,the complexity of the proposed decoding is reduced apparent-ly and the performance approaches to MLD decoding.
