Abstract:

An adaptive cooperative relay protocol is proposed, which can be adopted in future broadcast system. The outage probability performance of this protocol is analyzed using the moment generating function and inverse Laplace transform in the fading channel, and the asymptotic expressions for the outage probability are derived. This protocol is compared with the existing decode-and-forward protocol and the respective application scenarios are acquired. Combining numerical simulation and theoretical analysis, the working relay amount, the relay locations, the power allocation and their impact on the system performance are further analyzed. According to the results, the advantages and characteristics of this protocol are confirmed.

Key words: communication, decode-and-forward, amplify-and-forward, broadcast, outage probability
