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.)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息,导致了接收信息在某种意义上的浪费。软判决将接收电平量化,尽可能保存相应的信息,故可以提高译码性能。(soft descision decoding)
