本文详细介绍了MIMO雷达与MIMO蜂窝系统频谱共存的预编码器的设计。分别使用传统的切换零空间投影（SNSP）和新提出的切换小奇异值空间投影（SSSVSP）实现了零干扰或干扰最小的频谱共享。采用SSSVSP代替SNSP可以在一定程度上弥补预编码对雷达目标定位能力的影响，但增加雷达天线阵元数更为有效。
This paper details designing the precoder of a MIMO-radar spectrally-coexistent with aMIMO cellular system. Spectrum sharing with zero or minimal interference is achieved by using, respectively, the conventional switched null space projection (SNSP) or the newly proposed switched small singular value space projection (SSSVSP). Loss in radar target localization capability due to precoding can be compensated by using SSSVSP instead of SNSP to some extent but increasing the number of radar antenna elements is more effective.
