Liang Dong · Journal of Civil Aviation University of China · 2007
Based on the conventional Log-MAP algorithm for Turbo-codes decoding and the existing algorithm for simplifying Log-MAP,an improved algorithm is presented in this paper.Simulation results show that the proposed algorithm has performance very close to the Log-MAP algorithm for Turbo-codes decoding and can decrease the decoding complexity greatly at the same time.In addition,realization of the new algorithm by hardware is very easy.
