Turbo Equalization in BICM System Based on LDPC Coding
LV Qiang · Jisuanji fangzhen · 2009
Turbo equalization in BICM system based on LDPC coding realized the joint equalization and decoding.In the process of Turbo equalization algorithms,SIC has low complexity and less performance,which implies its poor ability to get the priori probability;MAP' performance is effective,but its complexity is high.A new algorithm called as MAP-SIC was proposed to link two algorithms,which got more priori probabilities through first MAP equalization before SIC equalization.Simulation results show that the algorithm has good tradeoff between the complexity and the performance.
