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.)

坐标变换，比较实用，程序完整，调试成功，可直接运行(shift_axis_to_origin2)

本程序主要分析了三种调制方式对放大器非线性的敏感度，从中得出结论，APSK信号最佳。(the procedures of the three main methods of modulation of the nonlinear amplifier sensitivity, draw conclusions, APSK best signal.)

估算信号时延估算信号延时估算信号时延估算信号延时(delay estimation and estimation delay delay estimation and estimation delay)

主成分分析法，主要用在光谱处理上的，包括可见和近红外光谱，对于其他的一些统计学数据也比较适用，包括原数据和处理后的数据(Principal component analysis (pca), mainly used on spectrum processing, including visible and near infrared spectrum, and is also applicable for other statistical data)

matlab经典教材并且其中有部分确实写得不错(Matlab classic textbook and some really well-written)

潮流计算实用数据，各种节点的，对潮流计算等电力计算机程序非常有用(Practical data flow calculation, the various nodes of the power flow calculation is very useful computer programs)
