一种基于正交空时块编码的单天线AF中继方案
|
摘要
提出了一种基于正交空时块编码的放大转发中继方案,该方案适用于中继节点配置单天线、目的节点配置任意数目天线的中继系统.并且对所提方案在瑞利衰落信道下进行了性能分析,推导了该方案接收信号信噪比的概率密度函数,以及不同调制方式下的误符号率.仿真结果验证了性能分析理论结果的正确性.
A simple amplify-and-forward(AF) relaying scheme based on Orthogonal Space-Time-Codes(OSTBC) is proposed,which applies to the scenario where only one single antenna at the relay and an arbitrary number of antennas at the destination.Also,the analytical performance of the proposed scheme is investigated in the context of Rayleigh fading channels.Specifically,the probability density function(pdf) of the received SNR is characterized and the symbol error rate(SER) of different modulation schemes is derived.Simulation confirms the validity of analytic results.
