spatial multiplexing

Multiple Input Multiple Output ( MIMO) antenna is a typical spatial diversity technique, by combining multiple antennas space-time block coding with orthogonal frequency division multiplexing ( OFDM) forming space-frequency block coding, In multipath channel fading conditions, which also can get additional frequency diversity gain.

多输入多输出天线既是一种空间分集技术，将多天线中的空时分组编码与正交频分复用技术相结合构成空频分组编码，在多径衰落信道条件下还可以获得额外多径分集增益。

We use different communication mechanisms in two areas, which use dynamic sleeping and listening in slight task area and employ time division multiple access according to the spatial multiplexing system in the intensity task area.

在这两个区域中分别使用不同的通信机制，轻度任务区采用动态睡眠唤醒机制，强度任务区内根据空间复用制度采用时隙分配制度。

To eliminate the co-channel interference, multiple receive antennas are generally used to provide spatial multiplexing.

为了消除共道干扰, 在接收端利用多天线提供空间复用是一种有效手段.
