Wang Zhongxun, Qing Mu · 2009
A Low-complexity Layered Decoding Algorithm for LDPC Codes is proposed. Our modified algorithm reduces the number of operations in variable nodes to lower LDPC decoder power consumption. The modified parts of LDPC decoder architecture is also described. Simulation results show that comparing with SPA and MSA, our algorithm reducing the number of operations nearly to 60% with little performance loss.
