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.
