Wu, Jun; Xu, Yufa; Luo, Hanwen; Su, Zhongyi The density evolution for layered decoding algorithms of low-density parity-check codes. (Chinese. English summary) Zbl 1174.94412 J. Shanghai Jiaotong Univ. (Chin. Ed.) 41, No. 6, 903-906 (2007). Summary: A density evolution procedure for low-density parity-check (LDPC) codes under layered decoding is presented. The convergence threshold and characteristic of layered decoding are analyzed and compared with common belief propagation and min-sum algorithm. It is found that the layered decoding does not improve noise threshold but it can reduce the decoding iteration by half.
