说明：  本人亲手做的一个matlab扩频通信系统simulink仿真系统。从发送端到接收到，每部分都相应得加了示波器或频谱仪，可以对照理论清楚观察到信号发生的变化。matlab6.5及以上版本上运行。
(I personally make a matlab Spread Spectrum Communication System simulink simulation system. Send-ended to receive from every part of a corresponding increase in the oscilloscope or spectrum analyzer can be clearly observed in the control theory of signal changes. matlab6.5 and above to run.)
