    信道的频率响应是时变的,设计最佳的固定的解调滤波是不可能的,因此,需要一种能补偿或减少接收信号中ISI的方法,这种ISI补偿方法称为均衡方法。 自适应均衡技术能够用来抵消由于信道带限或时间色散所导致的码间干扰,可以使通信系统更有效地利用信道带宽。 (Channel frequency response is time-varying, the best fixed design demodulation filter is impossible, therefore, need to be able to receive compensation or reduce the signal in the ISI method, the ISI compensation is called a balanced approach. Adaptive equalization techniques can be used to offset the channel band-limited or time dispersion caused by the inter-symbol interference can make communication systems more efficient use of channel bandwidth.)

    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.)
