New Outer Bounds on the Capacity Region of Gaussian Interference Channels
Recent outer bounds on the capacity region of Gaussian interference channels are generalized to m-user channels with m > 2 and asymmetric powers and crosstalk coefficients. The bounds are again shown to give the sum-rate capacity for Gaussian interference channels with low powers and crosstalk coefficients. The capacity is achieved by using single-user detection at each receiver, i.e., treating...
متن کاملA New Outer Bound and the Noisy-Interference Sum-Rate Capacity for Gaussian Interference Channels
A new outer bound on the capacity region of Gaussian interference channels is developed. The bound combines and improves existing genie-aided methods and is shown to give the sum-rate capacity for noisy interference as defined in this paper. Specifically, it is shown that if the channel coefficients and power constraints satisfy a simple condition then single-user detection at each receiver is ...
متن کاملSum Capacity of Degraded Gaussian Interference Networks
This paper determines the sum-capacity of degraded Gaussian K-user interference channels (IFCs). To this end, the paper first develops a family of genie-MAC (multiple access channel) outer bounds for Gaussian K-user interference channels. This family is based on existing genie-aided bounding mechanisms, but differs from current approaches in its optimization problem formulation and application....
متن کاملCapacity Bounds and High-SNR Capacity of the Additive Exponential Noise Channel With Additive Exponential Interference
Communication in the presence of a priori known interference at the encoder has gained great interest because of its many practical applications. In this paper, additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is introduced as a new variant of such communication scenarios. First, it is shown that the additive Gaussian ch...
متن کاملThe Capacity Region of the One-Sided Gaussian Interference Channel
The capacity region of the one-sided Gaussian interference channel is established in the weak interference regime. To characterize this region, a new representation of the HanKobayashi inner bound for the one-sided Gaussian interference channel is first given. Next, a new outer bound on the capacity region of this channel is introduced which is tight in the weak interference regime. This is the...
