Abstract

Abstract:

The performance of multi-user diversity gain (MDG) multiple input-multiple output (MIMO) fading channels is studied by the theoryof the order statistics and random matrices. It is found that the MDG decreases with the increase of the number of antennas. It is also pointed out that the total gain, which includes the MDG and spatial multiplexing gain (SMG), must be optimized when designing the multiuser MIMO communication systems.

Key words: multiple input-multiple output, channel capacity, scheduling, multiuser diversity, spatial multiplexing gain
