FSK matlab modulation

有源电力滤波器在产生指令电流时，基于瞬时无功功率的检测方法需要用到低通滤波器，本程序能够实现滑动滤波！(APF generating command current, based on instantaneous reactive power detection methods need to use a low-pass filter, the program can achieve sliding filter!)

数字图像频域滤波处理，分别进行二阶巴特沃斯(Butterworth)高通、低通滤波器。(Digital image processing frequency domain filtering, respectively second-order Butterworth (Butterworth) high pass, low pass filter.)

基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。 (BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding. )
