Abstract

The conventional cooperative protocols have to face some problems in practical broadcast and multicast systems because feedback channel is unavailable. An adaptive cooperative relay protocol, which can be adopted in future broadcast systems, is proposed in this paper. The outage probability performance of this protocol is analyzed over Nakagami-m fading channel, and the asymptotic expression of outage probability for proposed protocol is derived. It is compared with the conventional Decode-and-Forward and Amplify-and-Forward protocols. A combination of numerical simulation and theoretical analysis, including the optimal numbers of relays and the impact on the system performance are further analyzed for different channel states. According to these results, the advantages and characteristics of this protocol are confirmed.
