Abstract :
We investigate the performance of a DS/CDMA system with multiple-input multiple-output (MIMO) antenna processing in the downlink. We formulate the weights for the transmit and receive antennas by trying to obtain the optimum signal-to-interference-plus-noise ratio (SINR) in a frequency selective fading channel. The gain of our MIMO CDMA system with the formulated weights is illustrated by employing computer simulations for various configurations of antennas to determine the average bit error rate (BER) performance. The simulation results reveal that our system can reduce the average BER significantly
