Abstract

Relays serve as virtual antennas in wireless networks, fostering spatial diversity between the source and destination to enhance coverage, signal quality, and network reliability. Among the various relay-assisted communication approaches, amplify-and-forward (AF) is widely favored for its reduced computational complexity. The selection of an optimal relay is crucial for maximizing network performance, constituting a significant challenge in wireless communication. Hence, optimal relay selection has emerged as a pivotal area of research. In this thesis, we investigate the potential benefits of implementing relay selection schemes in AF relay networks featuring two source-destination pairs and two relays. Our analysis focuses on two relay selection approaches based on the performance metric, signal-to-noise ratio (SNR), and evaluating their impact on network performance. We propose a selective relay selection scheme tailored for dual-user systems, accompanied by a comparative performance analysis against random relay selection.
