Abstract: This paper investigates transceiver design, that minimizes the transmit power and balances all SINRs, for multiuser Multi-Input Multi-Output (MIMO) systems in the presence of imperfect Channel State Information (CSI). A worst-case SINR uplink-downlink duality is established under bounded channel uncertainties, and with the aids of this duality, a new scheme is proposed for the robust transceiver design. This scheme obviates convex optimization which uses interior-point iterative algorithm, and thus the whole system complexity can be greatly reduced. Numerical results show that the proposed algorithms exhibit the same performance when compared with the exiting robust algorithm.
