Minimum total MSE based transceiver design for single-user MIMO system

In this paper, we have developed minimum Total mean squared error (MSE) joint linear transceiver design for Single-user multiple-input, multiple-output (SU-MIMO) systems employing an improper constellation schemes. It assumes Imperfect channel state information (CSI) is available at both ends of transmitter and receiver and design transceiver is subject to a total power constraint. Channel mean and transmit correlation information are consider as channel state information. Joint design of transceiver is consider as optimization problem, the optimum closed-form precoder and decoder are derived by minimizing a total MSE based on modified cost function. The performances degradations due to imperfect channel estimation and/or transmit correlation are demonstrated and superiority of proposed method is proved by simulation results.
