摘　　要：本文分析了交织器在turbo码中的重要作用,以及随机交织器存在的缺陷,并提出了一种确定性交织器的设计方法。该交织器具有简明的解析表达式,易于实现。计算机仿真结果表明,该确定交织器可以获得的性能优于随机交织器的平均性能。In this paper we described the role of interleaver in turbo codes, analyzed the drawback of random interleaver. Then we presented a new class of deterministic interleavers, which have simple analytic expressions and are easy to be realized in applications. By simulation results, this kind of interleavers performed better than the average performance of a set of random interleavers.
