摘　　要：首先介绍了BPSK信号调制与解调的基本原理以及Nakagami衰落信道的统计特性;随后重点分析、推导了BPSK信号在通过Nakagami衰落信道后,经相干解调的平均误码率理论闭型表达式;最后在Matlab仿真平台中对该误码率闭型表达式进行了仿真验证,并总结了BPSK调制在Nakagami衰落信道中的误码性能。This paper firstly introduces the basic principls of BPSK signal modulation and demodulation, and the statistical charac- teristics of Nakagami fading channel. Then it focuses on the analysis and derivation of the BPSK signal in the Nakagami fading channel through the coherent demodulation of the average error rate theoretical closed form expression. Finally, the error rate closed form expression is simulated in the Matlab simulation platform, and the BER performance of BPSK modulation in Nakagami fading channel is summarized.
