分组Turbo 码在WiMAX 移动系统中的应用研究
Research on the Block Turbo Code for WiMAX Wireless Mobile System
WiMAX 系统(基于IEEE802.16e-2005 标准)信道编码方式中的分组Turbo 码(BTC)利用乘积编码方式,使得编码冗余度大大提升,针对突发噪声干扰信道,具有编码增益大,控制码字搜索范围降低复杂度,检错纠错能力强等特点。本文介绍了它的编码译码的算法原理,编译码器的结构。最后给出了仿真结果并分析其性能。
One of the channel code for WiMAX system (base on IEEE802.16e-2005)is BTC (Block Turbo Code).BTC has flexible frame size and code rate. It can achieve high efficiency coding. This paper introduced BTC encoding and decoding structure and algorithm. Finally, simulate the results under different modulation mode, code rate, analysis its performance.
