说明：  好不容易找不到的2812芯片在MATLAB环境下仿真的说明文件！ (After 2812 the chip can not be found in the MATLAB simulation environment documentation!)

用MATLAB编写与仿真了MSK信号，其中结合了自己写的快速傅立叶变换实现了MSK信号的调制还有解调，而且作为拓展，还加入噪声、通过带通滤波器、低通滤波器、载波信号等等。调制解调都很有用，画出的图也很漂亮规范。(Using MATLAB and the simulation of the MSK signal, which combines the fast Fourier transform to write their own modulation there demodulation of MSK signals, but also as a development, but also by adding noise, band-pass filter, low pass filter, the carrier signaland so on. The modem is very useful to draw the plan is also very beautiful and specification.)

matlab编写的正态云发生器与云拟合程序，其中有较详细的注释。(matlab prepared in the normal cloud generator and cloud fitting procedures, including more detailed notes.)
