    Abstract

    In this paper, we propose a transmit diversity scheme based on the vector perturbation for a multiuser multiple-input multiple-output (MIMO) broadcasting system. Our method is inspired by the fact that precoding process of the vector perturbation designed to suppress the multiuser interference causes a reduction of the transmitted signal power. In order to boost up the transmit power, we employ a non-integer based vector perturbation together with temporal transmit diversity. We show from the simulation on 10x10 multiuser MIMO system with 16-QAM modulation that the proposed method outperforms the repetition scheme as well as the vector perturbation.
