Noisy-Interference Sum-Rate Capacity for Vector Gaussian Interference Channels (1108.0870v1)
Published 3 Aug 2011 in cs.IT and math.IT
Abstract: New sufficient conditions for a vector Gaussian interference channel to achieve the sum-rate capacity by treating interference as noise are derived, which generalize the existing results. More concise conditions for multiple-input-single-output, and single-input-multiple-output scenarios are obtained.
