| 摘 要： | 提出了一种新的基于Turbo乘积码的编码协作通信方式.两个单天线用户通过共享自己的天线,形成一个虚拟的多天线系统,乘积码字的不同部分通过不同用户的上行衰落链路传输到基站,获得分集增益,来抵抗无线信道中衰落的影响.在相同的系统带宽和发送功率下,与非协作通信方式相比,该编码协作方式可显著提高系统的性能.

| Abstract: | A novel cooperative coding communication scheme in use of Turbo Product Code was presented.A virtual multi-antenna system was created by two mobile terminals with a single-antenna.Different parts of the product code word were transmitted to the base station through different users' uplink fading channels to obtain diversity gain.This scheme can effectively resist the fading effect in wireless channel.Compared with non-cooperative scheme,the system performance can be improved effectively in the same system b... |
