文章针对移动通信系统的特点提出一种新的随机交织算法来生成交织器进而取代传统的随机交织器 ,并对两者的生成难易程度、生成搜索时间、特性仿真等方面作了相应的比较 ,从而得出此种交织器从各方面综合考虑来说是优于传统的随机交织器的结论 ,尤其是在交织长度比较大的情况下前者的优越性就更显著。 Aiming at the characteristics of mobile communication system, this paper proposes a new random interleaving algorithm to generate interleaver and then replace the traditional random interleaver, and makes a corresponding comparison between the generation of the two, the generation of search time, the characteristics of simulation It is concluded that this kind of interleaver is superior to the traditional random interleaver in all respects. Especially in the case of relatively large interleaving length, the former’s superiority is even more remarkable.
