Cooperative networks allow the nodes relaying each other's messages to enhance the transmission reliability over wireless fading channels by achieving cooperative diversity. Among the various relaying protocols, the amplify-and-forward (AF) strategy is well studied for its simplicity. However, to collect the cooperative diversity, there are two main issues that the AF protocol is facing. One is that...
In this paper, we propose a novel amplify-and-forward relaying strategy for a two-hop single-relay network by incorporating an intentional peak power limit (IPPL). We show that the proposed strategy is not only practical for peak power constrained relay networks, but also helps to simplify the system at both relay and destination. With the proposed IPPL strategy, neither the relay nor the destination...
