摘　　要：系统的分集情况对系统的影响是很大的。这里我们研究了空间分集对系统性能的影响。本文推导了在空间分集的情况下非相干检测 FSK信号的误比特率 ,并利用了多径信道的衰落相关性模型 ,通过计算机模拟的方法具体研究了空间分集中天线的距离和散射体分布对的非相干检测 FSK信号误比特率的影响。Diversity of communication system have a great effect on system performance. In discussed this influence. Meanwhile, the BER formula is deduced for nonz coherent binary FSK with spacial diversity. Making use of correlated fading model, the influence of non coherent binary FSK's BER caused by antenna's distance in spacial diversity and distribution of dispersion objects by computer simulation are studied.
