一种Turbo码的快速Log-MAP译码算法
Fast Log-MAP decoding method of Turbo code
摘要
Abstract
Log-MAP algorithm is a simplified decoding method of Turbo code.The algorithm has the defects of high complexity and decoding delay.This paper presented a simplified log maximum a posteriori (Log-MAP) algorithm based on approximation theory.In the simplified algorithm, adopted the sectional optimal square approximation polynomial to calculate the correction function.Compared with the standard Log-MAP algorithm, the simplified algorithm has the advantages of low complexity,low decoding delay.And the decoding performance is similar to the standard Log-MAP algorithm.So it is more suitable for using inpractical engineering.关键词
