说明：  这是一个很好用的跳频通信系统的matlab仿真的资料，对于不会的同学很有效。simulink的设计电路方法很简单，(This is a very good use of frequency hopping communication system of MATLAB simulation data, for students will not be very effective. The circuit design method of Simulink is very simple)

it is a OFDM and QAM with dynamically X-QAM mdoulation scheme.

矩形波的产生，第一步定义特征参数，第二部产生矩形波，第三步画出波形(Square wave generation)
