多入多出智能天线技术

Multiple-Input Multiple-Output Smart Antenna Technique

多入多出或多发多收技术同时采用多天线发射和多天线接收,能够大大提高无线通信系统的容量和频谱利用率,是新一代移动通信系统必须采用的关键技术。文章叙述了多入多出的概念,给出了一个空时码的例子,并简述了多入多出技术的研究现状。

Multiple-input multiple-output (MIMO) or Multiple transmit and multiple receive (MTMR) technique employs multiple transmit antennas and multiple receive antennas simultaneously, which can greatly increase the capacity and spectrum efficiency of a wireless communications system. It is a key technique for the new generation of mobile communications. This paper presents the concept of MIMO, an example of space-time coding, and a brief introduction to MIMO's current research.
