Mixed Iteration Algorithm of LDPC Codes
Lin Cheng
Abstract
A mixed iterative decoding algorithm is proposed based on RRWBF algorithm and UMP BP-Based algorithm of LDPC code.This algorithm makes full use of the hard decision algorithm complexity low and soft judgment algorithm performance good advantage,the BER performance is realized,no drop in the premise,decode complexity is decreased obviously effect and the propagation delay is decreased.Simulation results show that,after carefully designed different iterations,mixed iteration algorithm than UMP BP-Based algorithm,decode complexity decrease the 30%.
