Abstract

In this paper, the weighted sum outage-rate maximization for time-invariant multiple-input multiple-output (MIMO) interference channels is considered. The cumulative distribution function (CDF) of outage events in MIMO interference channels is characterized under the assumption of Gaussian distribution for channel uncertainty. Based on the derived expression for the outage probability an iterative beam design algorithm for maximizing the weighted sum outage-rate under outage constraints is newly proposed. Numerical results show that the proposed algorithm shows good sum outage-rate performance.
