| 摘 要： | 针对一般的相关检测天线选择系统，分析了Rayleigh衰落信道接收端非理想信道状态信息下发送天线选择(AS)系统的误符号率(SER)性能，给出了数值积分形式的理论表达式。仿真结果表明，无论在理想或有误差的信道信息下，理论结果与实际的仿真结果都保持了一致。数值分析结果表明在低信噪比(SNR)区域提高信道状态信息的准确程度比增加天线数目更能提高天线选择系统的性能。

| Abstract: | The error performance for coherent detection transmit antenna selection (AS) system is investigated for a Rayleigh fading channel with imperfect channel state information at the receiver. The symbol error rate (SER) performance is expressed in numerical integration with finite limits for different signaling. Simulation shows that the proposed theoretical result matches the real system performance whether with perfect or imperfect channel information. The numerical results also show that the quality of channel state information dominates the AS system performance in lower signal to noise ratio (SNR) region. |
