K均值算法描述： 给定类的个数K，将N个对象分到K个类中去， 使得类内对象之间的相似性最大，而类之间的相似性最小。(K-means algorithm described: a given number of classes K and N objects assigned to the K-th class, so that objects within the class of the similarity between the maximum, while the similarity between the minimum class.)

本例程对十字形32QAM信号进行盲均衡处理，码间干扰可以降低到-30db，输出星座图更清晰(The routines of cross blind equalization 32QAM signal processing, inter-symbol interference can be reduced to-30db, output constellation diagram more clearly)

说明：  Direct Sequence Spread spectrum

该程序利用多相滤波结构实现了宽带信号的信道化，相比传统信道化方法，节省了资源，提高了效率。(The program uses the polyphase filter structure to achieve a broadband signal channelization, compared to traditional methods channel, save resources and improve efficiency.)
