New Outer Bounds on the Capacity Region of Gaussian Interference Channels

Abstract-- An outer bound on the capacity region of the twouser Gaussian interference channel is derived. The bound shows that for low power and small crosstalk coefficients the sum-rate capacity is achieved by treating interference as noise. The results are generalized to multiuser channels.
