Abstract

In this paper, the two-user interference channel with a half-duplex relay is studied. The relay does not hear one of the sources. The relay's transmission is beneficial for one of the receivers, whereas it is merely interference for the other. At the receivers the interference is either treated as noise, or if possible decoded first and subtracted from the received signal to enhance the direct transmission quality. Probability of outage for each user is computed and compared as the channels are assumed to be fading and no channel state information is available at the transmitters. Despite the fact that the relay causes interference to one of the users, it is shown that the relay is useful to both the receivers. ©2010 IEEE.
