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.)

KNN classifiers, training is training set, testing is test set, D is the distance, D=1 is mandistance D=2 is 欧氏距离 D=3是 infinite norm K is the number of selected neighbors
