无线通信中空分复用技术的研究现状

Research Status of Spatial Division Multiplexing in Wireless Communication

伴随着信息技术的不断革新,各类移动多媒体业务发展起来,同时,人们对于无线通信传输速度的要求越来越高,进而导致无线频谱出现日益匮乏的问题。近几年来,在空分复用系统的研究基础上,我国相关科学研究人员通过空间调制技术进行了传输速率的优化,并且没有更改原有的收发端天线数量。与此同时,在不影响传输质量的前提下大量运用了MIMO系统,完成了天线数量的增加工作,在这一研究基础上,笔者就无线通信中空分复用技术的研究现状展开分析,此次研究的目的是有效提升无线通信中空分复用技术的应用水平。

With the continuous innovation of information technology,all kinds of mobile multimedia services also develop.At the same time,the demand for wireless communication speed is becoming higher and higher,which leads to the increasingly scarce wireless spectrum.In recent years,based on the research of air division multiplexing system,the relevant researchers in our country have optimized the transmission rate through space modulation technology,and have not changed the original number of transmitter and receiver antenna.At the same time,without affecting the transmission quality of the use of a large number of MIMO system,the increase in the number of antennas,based on the research results,the research status of wireless communication control division multiplexing technology to analyze,the objective of this study was to have the level of application of wireless communication technology to enhance efficiency of hollow division multiplexing the.
