MIMO（多输入，多输出系统）的无线通信的智能天线技术的基础上发展起来的，它的主要特征是一个通信系统的使用多个天线配置来解决移动通信系统的发送和接收端 –以此来解决未来移动通信系统大容量高速率传输和日益紧张的频谱资源间的矛盾。和智能天线技术不同于系统在MIMO无线信道的发射天线，从任何到接收天线间的无线信道是相互独立或有很小的相关性。-Developed on the basis of smart antenna technology MIMO (multiple-input, multiple-output system) on wireless communication, its main feature is the use of multiple antenna configurations to solve the mobile communication system for sending and receiving end of a communication system- in order to the mobile communication system to solve the contradiction between large-capacity high-speed transmission and the increasing tension between spectrum resources in the future. And smart antenna technology is different　the system in MIMO radio transmitting antenna to a receiver　any radio channel between the antennas are independent or have very little relevance.
