摘要
Turbo码解码算法包括SOVA(softoutputviterbialgorithm) ,MAP (maxaposterior) ,以及LOGMAP算法 .其中LOGMAP算法兼有高性能和低计算复杂度的优点 .为了降低解码复杂度 ,对LOGMAP算法进行了模拟优化 ;为进一步减少解码时间 ,在解码过程中引入了滑动窗技术 .并对整个Turbo码解码过程进行量化模拟 ,得出了优化结果 .
Decoding algorithm of Turbo code includes SOVA, MAP and LOGMAP. LOGMAP algorithrn has good compromise between performance and complexity. In order to reduce decoding complexity, LOGMAP algorithms is simulated and optimized; and sliding window is applied to reduce decoding time further; then the whole decoding process is quantified for an optimal result.
