Spatial multiplexing and space diversity gain of a system can be extracted through MIMO technique.

多输入多输出(MIMO)技术可以为系统提供空间复用增益和空间分集增益。

Then, we study the precoding for space multiplexing MIMO-OFDM systems. Here, we propose an interpolation-based vector quantization precoding scheme.

然后，研究了空间复用MIMO - OFDM系统的预编码，提出了一种基于插值的矢量量化预编码方案。
