| 摘 要： | 以往MIMO通信的研究集中在分别提高分集增益或空间复用增益,但两者之间还可存在折中.本文主要介绍了MIMO通信中分集和复用机制,分析了两者之间的折中,并用这种折中对目前比较流行的几种空时机制做了比较.

| Abstract: | Most researches on MIMO communication focus on improving the diversity gain or the spatial multiplexing gain, which represent the abilities of resisting fading and collecting data by multiple antenna channels. In this paper, the mechanisms of diversity and multiplex are introduced. The Compromise between diversity and spatial multiplex reveals that both types of gains can be obtained simultaneously for a given multiple antenna channel. Several space-time mechanisms generally used are compared by using this tradeoff. |
