Channel-modeling
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 )
