3.算法概述
MIMO(Multiple-Input Multiple-Out-put)系统是一项运用于802.11n的核心技术。802.11n是IEEE继802.11bag后全新的无线局域网技术，速度可达600Mbps。同时，专有MIMO技术可改进已有802.11a/b/g网络的性能。该技术最早是由Marconi于1908年提出的，它利用多天线来抑制信道衰落。根据收发两端天线数量，相对于普通的SISO(Single-Input Single-Output)系统，MIMO还可以包括SIMO(Single-Input Multi-ple-Output)系统和MISO(Multiple-Input Single-Output)系统。
