| 摘 要： | 交织技术对通信中信道编码性能具有重要影响,WCDMA系统中就多次采用了交织技术来提高通信质量。分析了交织技术原理及交织器的各种类型,利用SIMULINK模块库建立了交织器性能仿真模型,对各种分组交织器、随机交织器,以及同一交织器在不同交织长度下进行了仿真,通过比较各种交织器在加性高斯信道传输下的误比特率,最终得出各种情况下不同结构交织器的性能、交织长度对通信的影响及相应的选择原则。

| Abstract: | The interleaving technology plays an important role in the channel coding of communication system.WCDMA often applies interleaver to improving the reliability of data transmission.This paper describes the interleaving technology in WCDMA.Then the simulation model is established with MATLAB,with which the performance of the designed interleaver is tested,and the simulation result is also given in this paper.Based on the in-depth study and simulation result,how to choice the interleaver is finally concluded. |
