| 摘 要： | 建立了基于Rayleigh多径衰落信道模型，详细分析了BFSK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，基于Rayleigh信道模型下的误比特率与信噪比成反比关系，且其误比特性能较高斯信道和伦琴信道的误比特性能更差．

| Abstract: | The paper establishes a model based on Multipath-Rayleigh-Fading-Channel,and analyzes in detail the BFSK relation between BER(Bit Error Rate) and SNR(Singal Noise Rate)in the BFSK,then compares their results in this article from the simulation results in MATLAB,it shows the inverse relation between BER and SNR under the model of Rayleigh Channel.Besides this,the performance of BER is worse than the AWGN Channel and the Rician Channel's. |
