Utilization of multiple antenna transmission technique is a potential solution to co-channel interference problems in coexisting environments. However, additional system cost and complexities associated with multiple antennas limit their application in CR Systems. In this paper we introduce antenna selection in cognitive MIMO systems and propose low complexity antenna selection algorithms. Wherein, using only a subset of available antennas to transmit or receive signal greatly reduce hardware cost and complexities of the CR transceivers; while keeping much of the benefits of multiple antennas.
