可以绘制变量的三维及四维散点图的matlab子程序，如饱和度等(plots the values in vector v colour coded at the positions specified by the vectors x, y, and z in a 3-D axis system. A colourbar is added on the right side of the figure.)

一些关于压缩感知（CS）的小程序，主要是压缩感知的重构算法(Some compression perception (CS) program, compressed sensing reconstruction algorithm)

用混沌形成一个序列然后对图像进行排序置乱和异或加密处理，效果很好(Forming a chaotic sequence and then sort of image scrambling and XOR encryption process, with good results)

用matlab实现的遗传算法与BP神经网络的优化算法。(Matlab genetic algorithm with BP neural network to achieve optimization algorithm.)

近年来随着移动互联网业务和物联网业务的兴起与 发展，用户对移动宽带业务需求越来越旺盛，对移动通信 网络的接入速率和质量要求也越来越高，原有基于码分多 址（CDMA）的3G及其增强技术未来将无法满足业务发展 需要，因此3GPP及3GPP2组织自2004年开始启动长期 演进（LTE）/空口演进（AIE，后改名为超移动宽带UMB）项 目，旨在通过引入一些关键技术，如正交频分复用（OFDM） 调制技术、多入多出（MIMO）技术、混合自动重传请求 （HARQ）、全IP扁平化架构及动态带宽分配等实现网络变 革，达到以下所述的网络性能，为移动宽带多媒体业务持 续发展提供技术保障。(Abstract:To meet the needs of mobile broadband services,LTE is being deployed and becoming ma－ tured,which includes key technologies such as OFDM,high-order modulation,HARQ,enhanced multi-antenna technologies,fast synchronization technologies,scalable control channel design,adap－ tive resource allocation,interference suppression technologies etc.Moreover,the discussion on LTE- Advanced has started,where technologies being considered includes aggregate multi-carrier,high－ er-order MIMO,smart relay,heterogeneous net－ work,multipoint collaboration as well as enhanced interference management.)
