Freq Shift Keying simulation in matlab

递推最小二乘算法，用matlab实现递推最小二乘参数辨识(recursive least square)

fuzzy_cluster模糊聚类分析，本函数使用的是直接聚类法，直接输出聚类信息，无返回值 输入参数data是需要分类的数据，将会对data的列分类，请输入数据前把需要分类的向量按列保存到矩阵data 输入参数numda是分类的分类点，如果不知道可以先省略，系统默认1-0依次减小用以方便判断分割点，然后用户再细分( Fuzzy_cluster fuzzy clustering analysis, the function uses the clustering method is direct, direct output clustering information, no return value input parameter data is needed to classify data, classification of data will be listed, enter the data before the need saved by the column vector classification matrix data to the input parameters numda profile classification point is, if you do not know can be omitted, in order to reduce the system default 1-0 split point for easy judgment, then the user is subdivided)

将图像分为nxn的分块,之后将各分块三个颜色通道的直方图平均化,最后进行离散余弦变化,分别提取各通道低频系数(The image into nxn sub-block after block of all three color channels of the histogram equalization, and finally the discrete cosine change, were extracted from the low frequency coefficients of each channel)

简易的基于小波变换滤波的程序及其演示程序(Simple filtering based on wavelet transform and its demo program)

信号DOA的估计算法,学习空间谱估计的同学可以参考(the signal DOA estimation algorithm, learning spatial spectrum estimation can refer students)

Different Modulation schemes are here! like ask, fsk, psk etc!
