摘要
Turbo码以其几乎接近Shannon理论极限的译码性能而成为目前为止最好的信道编码方案。为了减少信道传输引起的误码,提高传输可靠性,设计了一种基于SOVA算法的Turbo译码器,并介绍了Turbo译码器在数据协调中的应用。与传统的Turbo译码器相比,增加了两个权重模块,这样可提高译码的性能。同时,通过Matlab仿真,验证了所设计的Turbo译码器功能的正确性。
Turbo Codes has become the best channel encoding methods because its decoding performance is near to Shannon theoretical limit.In order to reduce the error bits caused by channel transmission and improve the reliability,this paper designs a Turbo decoder based on SOVA algorithm and introduces its application in the reconciliation.It improves the decoding performance by introducing two weighting modules.The simulation of Turbo decoder with Matlab is finished and its correctness of decoding function is proved.
