| 摘 要： | 介绍了无线信道的基本概念和特性,对幅度服从莱斯分布和瑞利分布的衰落信道的概率密度函数进行仿真。建立了多径衰落信道模型,详细分析了BFSK信号在多种衰落信道中误比特率与信噪比的关系,并进行了性能比较。仿真的结果表明,瑞利衰落信道的误比特性能较高斯白噪声信道和莱斯信道的误比特性能更差,且所建立的仿真方法可以作为多径衰落信道的分析方法。

| Abstract: | The basic concepts and the characteristics of mobile radio channel are introduced.The simulation of CDF and PDF of Rician and Rayleigh fading channel is done.The models of multipath fading channel are established.The relationship of BER and SNR in BFSK is analysed in detail.The simulation results in Matlab show that the performance of BER in Rayleigh channel is worse than AWGN and Rician channel,and the model's method can be applied to the method of analysis of multipath fading channel. |
