Abstract

In this paper, we propose an application of cooperative system in the ad-hoc network. Based on 802.11a PHY, a compatible physical layer protocol Relay-SISO is introduced for the single-relay single-antenna system. Using Non-orthogonal Amplify-and-Forward scheme, the proposed protocol boosts quality of transmission while works at the same data rate as 802.11a with little additional preambles. Simulation results reveal the feasibility of such cooperative scheme and a significant coding gain is observed at data rate 12Mbps.
