衰落信道上联合单个发收天线选择的性能分析

Performance Analysis of Joint Single Transmit and Receive Antenna Selection over Fading Channels

该文利用高斯Q函数的高次幂在衰落信道上的统计平均和矩生成函数法分别推导了多入多出Nakagami衰落信道上采用联合单个发送和接收天线选择的相干检测差分编码四相相移键控和M进制差分相移键控的平均误符号率的解析表达式。仿真和数值计算结果吻合。仿真和数值结果表明增大发送或/和接收天线数可以改善MIMO衰落信道上采用联合发收天线选择的差分编码四相相移键控和M进制差分相移键控的平均误符号率性能。

By using the results for infinite integrals involving higher-order powers of the Gaussian Q-function statistical averaged over fading channels and the moment generating function（MGF）-based analysis method,the exact and closed-form expressions for average SER of differentially encoded quadri-phase shift keying（DE-QPSK） with coherent detection and M-ary differential phase shift keying（MDPSK） in multiple input multiple output（MIMO） Nakagami-m fading channels employing joint single transmit and receive antenna selection（JSTRAS） were derived in this paper.The derived mathematical expressions are verified using computer simulation.The results of simulation and numerical calculation show that the average SER performance for MDPSK and DE-QPSK on MIMO fading channels with JSTRAS can be improved with increased number of transmit or / and receive antennas.
