Abstract:
1. A multiple input multiple output communication apparatus, comprising: a plurality of antennas for conducting a wireless communication; a switch for switching the plurality of antennas; and a control device for determining a combination of at least two antennas used for a multiple input multiple output communication from the plurality of antennas using signal to interference plus noise ratio information and spatial fading correlation information as a selection reference, and for outputting a selection signal for a selection of the at least two antennas to the switch, wherein: the plurality of antennas are divided into M branches each including two or more antennas; SINR C the control device uses an evaluation function for determining the combination of the at least two antennas, and varying depending on values of l 1 through l M , and selects l 1 -th through l M -th antennas from first through M-th branches where the value of the evaluation function is the maximum with the at least two antennas.
