摘要
Turbo码是近年提出的一种性能优越的信道编码 ,它在编码时采用并行的系统反馈卷积码 (recursivesys tematicconvolutional)编码器 ,解码时则主要采用MAP(maxaposterior)算法 .在本文中 ,笔者尝试将滑动窗 (slidingwindow)技术运用到Turbo码的解码过程中 ,以减少Turbo码的解码延迟 ,并在此基础上提出了一种改进方案 ,在模拟中获得了较好的效果 .
Turbo code is a new class of binary parallel concatenated recursive systematic convolutional codes which is normally decoded by MAP algorithms. In this article, a new sliding window was presented in order to reduce the Turbo decoding time, and in the simulation,it performed better than the normal sliding window.
