3、 瑞利信道中的调制解调、信道估计:
(1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能,并画出比特信噪比与误码率的关系曲线。
(2) 在单径瑞利信道中,请设计一种时分的导引辅助的信道估计方法,用Simulink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(1)的曲线进行对比。
(3, the Rayleigh channel modulation and demodulation, channel estimation:
(1) Please derive the single-path Rayleigh channel coherent demodulation of BPSK BER performance theory, and draw the signal to noise ratio and bit error rate curves.
(2) single-path Rayleigh channel, please design a division of the guide-assisted channel estimation method, using Simulink simulation, measurement of the BER performance of BPSK, draw-bit signal to noise ratio and bit error rate curve, and with (1) of the curves were compared.
