Abstract

Abstract:

For research of the capacity properties and the practical performances of the interference channel with relay, the ability of simultaneously obtaining the multiplexing gain and the diversity gain in the oneside interference channel with relay are analyzed. Based on oneside interference channel with relay with the cognitive relay model, the channel capacity and the outage probability are also analyzed and the expressions are given. The diversity multiplexing tradeoff of the oneside interference channel with relay in the high signal to noise ratio is thereafter derived. Simulation shows that, compared with the one in the Zchannel, the relay can increase both the multiplexing gain and diversity gain simultaneously.

Key words: interference channel, cognitive relay, outage probability, diversity gain, multiplexing gain
