LTEandLTE_Advanced
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.)

层次分析法(Analytic Hierarchy Process,简称AHP)是将与决策总是有关的元素分解成目标、准则、方案等层次,在此基础之上进行定性和定量分析的决策方法。该方法是美国运筹学家匹茨堡大学教授萨蒂于20世纪70年代初,在为美国国防部研究"根据各个工业部门对国家福利的贡献大小而进行电力分配"课题时,应用网络系统理论和多目标综合评价方法,提出的一种层次权重决策分析方法。(AHP (Analytic Hierarchy Process, referred AHP) is always the element of the decision-making related to broken down into goals, guidelines, programs and other levels, on this basis for decision-making qualitative and quantitative analysis. This method is the U.S. Operations Research Professor at the University of Pittsburgh Satie early 1970s, the U.S. Department of Defense for research, " according to various industrial sectors contribution to national welfare and power sharing" topic, application network systems theory multi-objective and comprehensive evaluation methods, the right to propose a hierarchical weight decision analysis methods.)
