通信中QAM调制，用的是16QAM，分为同相路、正交路的调制。将比特串串并变换后分别调制。(QAM modulate)

能够修改交织深度，来实现任意长度的交织，采用802.11a的方案，实现分组交织(Interleaving depth can be modified to achieve any length intertwined, using 802.11a solution, implementing the packet interleaving)

Example of application of difference circuits at numerical solution of the equations with partial derivatives

KMEANSK Performs K-means clustering given a list of feature vectors and k The argument k indicates the number of clusters you want the data to be divided into. data_vecs (N*R) is the set of R dimensional feature vectors for N data points. Each row in data_vecs gives the R dimensional vector for a single data point. Each column in data_vecs refers to values for a particular feature vector for all the N data points. The output data_idxs is a N*1 vector of integers telling which cluster number a particular data point belongs to. It also outputs centroids which is a k*R matrix, where each rows gives the vector for the cluster center. If we want to segment a color image i into 5 clusters using spacial and color information, we can use this function as follows:
