中文说明：GSM中GMSK调制信号的产生，研究生时的现代信号处理的作业，包括随机梯度算法，相对梯度算法，双向PCS控制仿真，MIMO OFDM matlab仿真,这个有中文注释，看得明白。
English Description：
GSM GMSK modulation in signal generation, when modern signal processing operations, including stochastic gradient algorithm, algorithm of relative gradient, bi-directional simulation for PCS, MIMO OFDM simulation of MATLAB, the Chinese comments, understand it.
