摘　　要：介绍了LTE Turbo编译码方法,基于硬件实现对编码和交织器的计算进行了简化,提高了编码效率,利用Matlab仿真分析性能,分别采用Log-MAP算法和Max-Log-MAP算法进行译码,实现时结合项目需求综合考虑采用了误码率性能较好的Log-MAP算法。In this paper, the method of LTE Turbo coding and decoding is introduced, the methods for reducing the computational complexity of coding and interleaver are proposed based on hardware implementations, and the coding efficiency is increased. The performance by simulation of Matlab is analyzed, the Log-MAP algorithm and Max-Log-MAP algorithm are used by the LTE Turbo decoder, considering the requirement of the project adopt the Log-MAP algorithm with better bit error rate performance.
