 结合理论课讲解基于Matlab建立不同信道模型：高斯信道、Rayleigh信道，Recian信道及多径衰落信道模型；
 给出QAM/GMSK调制方式下在上述信道模型下的误码率性能分析，分析比较两种调制方式的优缺点；
 分析信道参数、信噪比对误码率性能的影响； (Based on Matlab, we construct different channel models: Gaussian channel, Rayleigh channel, Recian channel and multipath fading channel model.
The error rate performance analysis of QAM/GMSK modulation mode under the above channel model is given, and the advantages and disadvantages of the two modulation modes are analyzed and compared.
　Analysis of channel parameters, signal to noise ratio on the impact of bit error rate performance )
