A Novel Robust Transceiver Design for MIMO Interference Channel

摘要

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