摘　　要：利用MATLAB提供的可视化工具箱Simulink构建加性高斯白噪声、多径瑞利衰落和伦琴衰落三种信道传输系统。通过仿真给出了三种系统的误码率与信噪比的关系曲线,结果证明瑞利衰落信道对系统的误码率性能的影响较大,而且伦琴信道传输BFSK信号性能优于瑞利衰落信道。Construct the Additive White Gaussian Noise, Muhipath Rayleigh Fading Channel and Muhipath Rician Fading Channel transmission system with SIMULINK, a visible tool provided by MATLAB. Throng simulation, the curve about three systems＇ bh error rate and SNR were given. The research result prove that Muhipath Rayleigh Fading Channel has larger influence on the system＇s bit error rate, Multipath Rician Fading Channel＇s performance is better than Muhipath Rayleigh Fading Channel on transmission BFSK signal.
