Sum Capacity of MIMO Interference Channels in the Low Interference Regime
Sum Capacity of MIMO Interference Channels in the Low Interference Regime
Using Gaussian inputs and treating interference as noise at the receivers has recently been shown to be sum capacity achieving for the two-user single-input single-output (SISO) Gaussian interference channel in a low interference regime, where the interference levels are below certain thresholds. In this paper, such a low interference regime …
