摘要
在传统的Turbo译码算法Log-MAP的基础上,提出改进的SW-Log-MAP算法。仿真表明,改进算法的算法复杂度和存储空间比传统的Log-MAP减少了很多,但是性能几乎没有损失。
Derived from the conventional Log-MAP decoding algorithm of turbo code, the improved SW-Log-MAP algorithm is put forward. Based on simulation,the conclasion is drawn that computational complexity and storage requirement of the improved SW-Log-MAP are reduced with no performance degradation.
