摘要
Multiple transmit (Tx) and multiple receive (Rx) antennas systems, referred to as multiple input multiple output (MIMO) systems, have been proposed to achieve higher data rates in wireless communication systems. In this paper, we investigate joint optimization of transmitter and receiver for MIMO system when the channel information is available at both transmitter and receiver. We discuss the problem of designing Tx and Rx filter based on minimum bit error probability criterion. We first derive the optimum Tx and Rx filter for the special case of two input data symbols. Based on this optimum filter, we propose a Tx and Rx filter optimization for the general case of input data symbols. The performance of the proposed Tx and Rx filter is compared with that of the conventional minimum mean-squared error (MMSE) filter. Performance analysis shows that the proposed filter provides significant improvement over the MMSE filter in bit error probability.
