Abstract :
In order to wisely use the degrees of freedom which a multi-input multi-output (MIMO) system offers, it is necessary to identify and quantify the possible gains in performance one can expect from MIMO signal processing. In this paper, we derive measures which allow to quantify the amount of antenna gain, diversity gain, and multiplexing gain of a MIMO system. It turns out that it is impossible to maximize all three gains, or any pair of two gains at the same time. The necessary trade-off between performance gains is demonstrated
