非线性放大器对发射信号的影响，与调制方式密切相关。不同的调制方式，所得到的时域波形是不同的，如用于欧洲移动通信的GSM制式，该制式采用了高斯滤波的最小偏移键控（GMSK），是一种相位平滑变化的恒定包络的调制方式，因此可以用非线性放大器来放大，不存在包络失真问题，也不会因为频谱再生而干扰邻近信道。
-Non-linear amplifier on the transmit signal of the impact is closely related with the modulation method. Different modulation methods, the resulting time-domain waveforms are different, such as for the European GSM mobile communications standard, the standard use of Gaussian minimum shift keying filter (GMSK), is a smooth change in the phase constant envelope modulation, so you can use non-linear amplifier to amplify, there is no envelope distortion, nor because of spectral regrowth and adjacent-channel interference.

the Capacitated Vehicle Routing Problem
The CVRP is a hard combinatorial optimisation problem. The scenario is that a set of depots contains goods to be delivered to customers by a fleet of trucks. Each customer wants a certain integer amount of goods called their demand and each truck can only carry a certain amount called its capacity. All trucks have the same capacity. The objective is to find a set of routes, one for each truck, which minimises the total distance travelled by all trucks (the 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

k-means 算法接受输入量 k ；然后将n个数据对象划分为 k个聚类以便使得所获得的聚类满足：同一聚类中的对象相似度较高；而不同聚类中的对象相似度较小。聚类相似度是利用各聚类中对象的均值所获得一个“中心对象”（引力中心）来进行计算的。
Matlab 源代码，以兰花数据集作为测试对象。-k-means algorithm to accept input k then n data object is divided into k-clustering in order to make available to the cluster to meet: the same objects in clustering high similarity and objects in different clustering the similarity smaller. Cluster similarity is the use of the clustering of objects by means of a

人脸表情识别实现
采用图片库，在检测阶段，首先对图片进行灰度化处理，光照补偿，然后进行去噪，进行图片边缘化处理，在进行归一化，使得图片一致，在特征提取过程中用PCA主成分分析法，对图片特征进行提取，然后投影在向量空间中，最后对测试图片进行最近距离的计算，从而选定最符合的表情模型。
