| 摘 要： | 基于Alamouti提出的BPSK调制下空时分组码在Rayleigh衰落信道中的简单分集方案。推导出多发射和多接收天线系统中正交空时分组码在Nakagami衰落信道的BPSK调制下的比特差错率的最小距离球界,并推广到在高阶调制下衰落信道中系统符号差错率的性能。仿真分析和比较了空时分组码的多天线系统中发射和接收天线分集增益,以及信道相关参数的变化对系统误比特性能的影响。

| Abstract: | Based on studying the performance of Alamouti’s two transmit diversity scheme for BPSK modulation over Rayleigh fading channels,we analyzed the error probability of space-time block code and derived the minimum distance sphere bound of the symbol error rate for MPSK modulation over Nakagami fading environment.Simulations demonstrate that the good performance of space-time block code by using multiple transmit antennas and receive antennas over the Nakagami fading channels. |
