Abstract/Summary In this paper, a closed-form expression for Bit Error rate (BER) of a Multiple-Input Multiple-Output (MIMO) system employing the Minimum Mean Square Error MMSE channel estimation method is derived. The numerical results show that when the Channel State Information (CSI) is free of estimation errors BER decreases when the number of receive antennas increases. However under imperfect CSI, BER is getting worse when the number of Rx antennas is increased. In order to improve BER, a fast antenna selection scheme is proposed. The obtained numerical results prove that the proposed antenna selection scheme indeed improves the MIMO system BER performance. ©2010 IEEE.
