摘要 在传统的Turbo译码算法Log-MAP的基础上进行改进,提出了SW-Log-MAP译码算法。仿真表明:在保证译码性能的前提下,改进算法大大降低其运算复杂度,并将滑动窗的方法应用于译码模块,大大减少了存储空间。 Derived from the conventional Log-MAP decoding algorithm of Turbo code, the improved SW-Log-MAP algorithm is put forward, Simulation can conclude that the improved arithmetic greatly reduces computational complexity and storage requirement by sliding-window algorithm without performance degradation.
