— In this paper, we consider a 2-hop wireless diversity relay network. We explore transmit power allocation among the source and relays to maximize the received signal to noise r...
—A set of distributed non-cooperating relay antennas is known to be capable of orthogonalizing multiple sourcedestination pairs in space by coherent amplify-and-forward (AF) rela...
In this paper, we study the application of physical layer network coding to the joint design of uplink and downlink transmissions, where the base station and the relay have multip...

Abstract—Using cooperative transmission, two or more singleantenna users can share their antennas to achieve spatial diversity in a slow fading channel. One relaying protocol tha...
