Optimal antenna selection in MIMO systems with space-time block coding

Optimum antenna sub-set selection in MIMO systems is an attractive cost red ucing technique. In this paper we develop an optimal antenna sub-set select ion technique to be used in conjunction with space-time block codes over a MIMO link to optimize link error performance over a fading channel. We stud y the case when antenna sub-set selection is applied either at the transmit ter or the receiver. We provide analytical results for substantial improvem ent ill average SNR and outage capacity when antenna sub-set selection is u sed. Simulation results that verify our analytical prediction are also pres ented.
