维特比译码仿真程序 cnv_encd.m　卷积编码程序 viterbi.m　　卷积译码程序 其它的是viterbi.m中用到的子函数(Viterbi convolutional coding cnv_encd.m simulation program procedures viterbi.m other convolutional decoding procedure is used in viterbi.m Functions)

本代码是基于k-mean聚类的关键帧提取代码，是用matlab来实现的。(The code is based on k-mean clustering key frame extraction code, using matlab to achieve.)

利用MATLAB程序仿真轴承内圈不同故障程度信号。仿真信号X由故障信号 与白噪声r两部分构成(Use MATLAB program to simulate the signal of different failure degree of bearing inner ring. Simulation signal X consists of two parts: fault signal and white noise r)

谱减法实例，已经做过实验，可以运行，只要载入数据即可(Spectral subtraction instance, has done the experiment, you can run, as long as the data can be loaded)
