Abstract
A three-phase transmission scheme for the linear four-node half-duplex wireless relay network is proposed. In each of its two cooperative phases, the setting is equivalent to the broadcast channel with cognitive receiver, whose capacity region is determined. Based on that result, the three-phase scheme is shown to be capacity achieving. Its performance is compared with two suboptimal schemes.
