Abstract:
A robust vector precoding scheme is proposed for imperfect channel in multiuser MIMO system. In the nonideal channel model, the transmit side only knows imperfect channel state information, i.e. the mean value of the channel estimation and the 1st and the 2nd order statistic value of the estimation error. Based on this channel model, the robust VP precoding matrix and perturbation vector are obtained by minimizing the mean square error of the transmitted and received signals. Simulation results show that the new precoding scheme outperforms the conventional scheme.
