Transmission rates over state-dependent diamond channel

This study considers the state-dependent diamond channel (DC) in which the transmission is affected by another source, the interferer. Basically, the transmission from the source to its destination is carried out with the help of two parallel relays. All nodes forming the DC are assumed to be cognitive in the sense that these nodes can estimate the interference signal and then cooperate to remove its effect. For this channel model, the authors initially establish the achievable rate in the case that different noisy versions of the interference signal are non-casually available at all nodes. Then, a three-phase practical transmission scheme is proposed such that these nodes may estimate the interference signal causally and then start transmission. The authors' numerical results show that it is sufficient to have the interference signal at both the relays to get an interference-free achievable rate. In addition, the achievable rate of the DC channel is inversely proportional to the interference coding rate.
