Abstract

This paper presents a new improved algorithm to reduce the considerable complexity of decoding process of Turbo codes.It can accelerate decoding and improve decoding performance through the threshold decision of extrinsic information.In addition

approach to determine the specific threshold value was presented.The results of computer simulation have shown that the proposed algorithm has better performance and lower complexity than the traditional Maximum

A-Posteriori

decoding algorithm.
