Channel Feedback Algorithms Based on Opportunistic Beamforming MIMO Systems
基于随机波束成形MIMO系统的信道反馈算法

MIMO is one of the most important techniques in the future wireless communication systems.Opportunistic beamforming can significantly improve the performance of MIMO systems by exploiting the feedback information that conveys the channel quality.But,the feedback information expenses a substantial amount of wireless resource and decreases system efficiency.To save the feedback load,two partial feedback algorithms were proposed and named thresho-ld feedback and best feedback respectively.The theory expression...
