In this paper, a selection of different multiantenna (MIMO) systems will be presented. The adopted MIMO configurations with four and two transmit antennas and two receive antennas are selected according to the IEEE 802.16e standard: diversity scheme, hybrid diversity scheme and spatial multiplexing. Computer results present an adaptive selection strategy among the considered MIMO schemes along with their performance.
