说明：  GSM手机信号的基带数字信号调制MATLAB仿真算法，可以直接生成代码载入FPGA板中，这个算法是公司应用过的，肯定可行。请别乱传。
(Baseband digital signal modulation MATLAB simulation algorithm GSM mobile phone signal, you can generate code directly loaded into the FPGA board, the algorithm is applied over the company, and certainly feasible. Please Freeze pass.)
