多进制数字相位调制也称多元调相或多相制。它利用具有多个相位状态的正弦波来代表多组进制信息码元,即用载波的个相位对应于组进制信息码元。如果载波有2k个相位，它可以代表k位进制码元的不同码组。多进制相移键控也分为多进制绝对相移键控和多进制相对(差分)相移键控。(This m-file simulates mpsk (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).)

K-means算法是最为经典的基于划分的聚类方法，是十大经典数据挖掘算法之一。K-means算法的基本思想是：以空间中k个点为形心进行聚类，对最靠近他们的对象归类。通过迭代的方法，逐次更新各簇的形心的值，直至得到最好的聚类结果。(K-means algorithm is the most classical partition-based clustering method and one of the ten classical data mining algorithms. The basic idea of K-means algorithm is to cluster k points in space and classify the objects closest to them. Iteratively, the values of centroid of clusters are updated one by one until the best clustering results are obtained.)

扫雷游戏先说下原理，原理其实很简单，设法获得“雷区”的数据，然后通过模拟鼠标动作，点击雷区上非地雷的的格子，就搞定了:) 所以技术难点只有三个：获得雷区数据、找到扫雷程序和模拟鼠标动作。 -game

一个大家经常玩的桌面小游戏，就是贪吃蛇，我觉得还是挺有意思的。希望你们会喜欢。-one we used to play small desktop games, Snake is, I think it is quite interesting. I hope you will like.
