Abstract

Abstract:

For the problem on a twouser Gaussian interference channel, Gaussian interference channel with a common relay is considered based on cooperation communication technology. Two system models of Gaussian interference channel with a common relay are proposed. For each of two system models, upper and lower bounds on achievable sum rate are studied. Performances corresponding to different relay locations are compared and proved by simulation results. The performance of two system models proposed here outperforms the communication system without relay.

Key words: interference channel, relay, achievable sum rate
