| 摘 要： | Turbo码是近年来提出的一种高性能的信道编码.Turbo码交织器的设计是Turbo编解码器设计中的关键.分析了Turbo码对交织器的设计要求,根据m序列的伪随机特性,提出了一种利用m序列生成器的交织器设计.这种交织器可以大幅降低对寄存器资源的占用,而且结构简单易于实现.仿真实验表明,该交织器的性能介于查表法伪随机交织器和行列交织器之间.

| Abstract: | Turbo code is a high performance channel code recently presented. The design of interleaver is the key in the design of Turbo coder. The requirements of Turbo code on its interleaver are analyzed, and a new approach of interleaver using m -sequence generator is proposed based on the pseudo randomness of m -sequence. This interleaver has simple structure, reduces the usage of registers significantly and performs between lookup-table pseudo-random interleaver and row-column interleaver. |
