Abstract: This paper discusses antenna subset selection in MIMO wireless ystems. The subsets of transmit and receive antennas are selected so as to maximise the channel capacity. First of all, we establish the relationship between the multiplexing gain and the diversity gain achievable with adaptive antenna subset selection. Second, we indicate a selection rule that allows to achieve a full diversity advantage with a reduced computational effort, by decoupling the combined transmit/receive selection into the separate selection of transmit/receive subsets. Finally, we study the performance of practical systems with antenna selection in the context of high throughput MIMO-OFDM WLAN.
