| 摘 要： | 交织器的设计对提高Turbo码的性能有着重要的影响。首先研究了QPP交织器的设计原则,给出了具有良好S距离特性的QPP交织的设计方法。仿真结果表明:设计得到的QPP交织器的性能并不比通过随机搜索得到的一般S-随机交织器性能差。

| Abstract: | Interleaver design is vital to the performace of Turbo codes.This paper dicusses the design principle of QPP interleaver,then gives the way of designing QPP interleaver with favorable S distance property.The simulation results show that the performace of such QPP interleaver is not worse than that of ordinary S-random interleaver through random search. |

| Keywords: | Turbo codes S distance property quadratic polynomial permutation(QPP) |
