摘要
MIMO(多输入,多输出)是一种用于无线通信的天线技术。它利用多天线来抑制信道衰落,在不增加带宽和天线发射功率的情况下,成倍地提高无线通信系统的信道容量,降低误码率。本文主要介绍了MIMO技术的理论基础,当前MIMO的发展,以及它与CDMA技术结合的应用前景。
MIMO （multi-inputs, muhi-outputs） is used for wireless communicative air wire technology.The technologies can multiply the channel capacity and reliability of wireless communication system with the same frequency at no additional power expenditure,Reduce the error rate.The paper introduces the theoretical basis of MIMO technology, the development of MIMO technology, the applications of MIMO at present and its＇ prospect.
