说明：  在单径瑞利信道中，设计一种时分的导引辅助的信道估计方法，用Simulink和m语言进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比(In the single path Rayleigh channel, a time-division guidance aided channel estimation method is designed. The simulation is carried out with Simulink and M language. The BER performance of BPSK is measured, and the relationship curve between bit signal-to-noise ratio and BER is drawn, and compared with the theoretical BER curve)
