说明：  此代码是用matlab软件仿真PAM4信号的传输，自动生成传输数据，在接收端做基本的信号处理，计算出误码率。(This code uses MATLAB software to simulate the transmission of pam4 signal, automatically generate the transmission data, do basic signal processing at the receiving end, and calculate the bit error rate.)

用matlab实现中值滤波 用matlab实现中值滤波(Median filter implementation using matlab to achieve median filter with matlab)

一些常用的小程序，具有较高的可重用性。另外都可以运行。(Small number of commonly used procedures, have a high reusability. Also can be run.)

FCM Data set clustering using fuzzy c-means clustering. [CENTER, U, OBJ_FCN] = FCM(DATA, N_CLUSTER) finds N_CLUSTER number of clusters in the data set DATA. DATA is size M-by-N, where M is the number of data points and N is the number of coordinates for each data point. The coordinates for each cluster center are returned in the rows of the matrix CENTER. The membership function matrix U contains the grade of membership of each DATA point in each cluster. The values 0 and 1 indicate no membership and full membership respectively. Grades between 0 and 1 indicate that the data point has partial membership in a cluster. At each iteration, an objective function is minimized to find the best location for the clusters and its values are returned in OBJ_FCN.
