On Achievable Rates for Interference Relay Channel with Interference Cancelation
Onur Sahin, Elza Erkip · 2018 52nd Asilomar Conference on Signals, Systems, and Computers · 2007
We consider two interfering source-destination pairs that are assisted by a common relay. The relay simultaneously helps both sources to improve communication rates. We provide coding strategies that combine dirty paper coding, beamforming and interference reduction techniques at the relay and give an achievable rate region for Gaussian interference relay channel. The region shows significant rate gain can be obtained by performing generalized dirty-paper coding at the relay.
