On the noisy interference regime of the MISO Gaussian interference channel

In this work, we consider the two-user Gaussian MISO interference channel. We derive a criterion for sum-rate optimality of treating interference as noise at the receivers, which generalizes recent results for the SISO case [1]-[3].

Description
Summary:In this work, we consider the two-user Gaussian MISO interference channel. We derive a criterion for sum-rate optimality of treating interference as noise at the receivers, which generalizes recent results for the SISO case [1]-[3]. In contrast to those results, however, the criterion is not in closed form. For the case where single-mode beamforming is applied at the transmitters, we propose a practical decision algorithm that will decide whether optimality holds for a given channel.
