分布式Turbo码在无线中继网络的协作通信

Cooperative Communication of Distributed Turbo Codes in Wireless Relay Networks

为了评估Turbo码在无线中继协作通信系统中的传输性能,通过分布式Turbo码编码及联合迭代解码的方法研究Turbo码通信在无线中继网络协作通信。分布式Turbo码有源端、中继端、接收端三个通信端口,分别将两个相同系统递归卷积码放置在源端和中继端,信号在两个时隙内协作传输到接收端口进行联合迭代译码。通过选择二进制相移键控(BPSK)的信号调制方式并采用Matlab来编译蒙特卡罗模拟,结果表明:分布式Turbo码及其相应解码协作通信方案成功地实现了较低误码率。

To evaluate the transmission performance of Turbo code in wireless relay cooperative communication system,the cooperative communication of Turbo code in wireless relay network is studied by means of distributed Turbo code encoding and joint iterative decoding.The modulation schemes chosen is Binary phase shift keying(BPSK).Monte Carlo simulation results show that the distributed Turbo code and its corresponding decoding for cooperative communication scheme successfully achieve lower bit error rate.It can be seen that the cooperative communication scheme proposed in this paper is innovative and desirable.
