A Rate Region for the Interference Channel with Point-to-point Codes

Yong Li, Xiaoxia Song, Baoming Bai

Abstract


As point-to-point codes are widely exploited by most communication systems, it's performance limits under all kinds of communication channels are very important for the communication system. In this paper, we derive an achievable rate region for the 2-user interference channel with point-to-point codes. The achievable rate region are obtained by taking into account of all the coding strategies including treating interference as noise, time sharing, and simultaneous decoding. Both theoretical and numerical results show that the rate region is strictly larger than those via any a single decoding rule. And it is the best rate region for the interference channel with point-to-point codes.

Keywords


interference channel, capacity region, achievable rate region, point-to-point codes.
