| 摘 要： | 并行级连卷积码（Ｔｕｒｂｏ Ｃｏｄｅｓ）是近年来在编码理论上的一个重大突破，其性能与信道容量极限的差距可小于１ｄＢ，有着极其广阔的应用前景，而其独特的迭代译码方法更成了编码界和通信界讨论的热点。讨论了Ｔｕｒｂｏ Ｃｏｄｅｓ的编译码原理及ＢＣＪＲ算法，比较了ＳＯＶＡ，Ｍ－ＢＣＪＲ及Ｔ－ＢＪＣＲ等几种简化译码算法的性能，并对后两者的工程应用进行了探讨。

| Abstract: | Turbo Codes is a breakthrough in coding theory in recent years with its performance discrepancy to channel capacity less than 1dB,and its iterative decoding method became the highlight of coding and communications fields. This paper discusses the principle of Turbo Coding & Decoding and BCJR algorithm, states the engineering application of simplified schemes:SOVA,M BCJR after comparing their performance and complexity. |
