In this paper Bit Error Rate (BER) performance is analyzed for Multiple Input-Multiple Output (MIMO) communications systems using antenna selection in the transmitter, Maximal Ratio Combining (MRC) and Linear De-correlating Detector (LDD) in the receiver in Wide band Code Division Multiple Access (WCDMA) downlink channels with correlated Nakagami fading. The MRC maximizes signal to noise ratio of the received signal, then the LDD cancels out Multiple Access Interference (MAI). Theoretical results are validated using computer simulations. Moreover, a pilot based estimation method is proposed to jointly estimate the channel gains and the rows of the LDD operator.
