A Novel Robust Transceiver Design for MIMO Interference Channel

This paper focuses on robust transceiver design for throughput enhancement on the interference channel (IC), under imperfect channel state information (CSI). In this paper, algorithm is proposed to improve the throughput of the multi-input multi-output (MIMO) IC. Each transmitter and receiver has respectively M and N antennas and IC operates in a time division duplex mode. In the proposed algorithm, each transceiver adjusts its filter to minimize the estimated variance of signal-to-interference-plus-noise ratio (SINR). Taylor expansion is exploited to approximate the effect of CSI imperfection on variance. Monte Carlo simulations are employed to investigate improvement in sum rate performance of the proposed algorithm and the advantage of incorporating variation minimization into the transceiver design.
