Performance Analysis of Combined Cooperative Diversity and Multiuser Diversity

Abstract

This paper presents the combined use of cooperative diversity and multiuser diversity. Round robin based fair scheduling (RRFS) is used to achieve the benefit of Cooperative diversity and Multiuser diversity in multisource and multi-relay amplify and forward relay networks. Multiuser diversity uses user scheduling scheme to select high quality channel users based on the channel state information. This cause transmission unfairness .In this paper, a Round robin scheduler is used to achieve fairness among users .A joint source relay pair selection is employed in the relay phase, which helps the best relay to transmit the worst source in each relay time slot.
