Performance Analysis of AF Relaying Systems with Partial Relay Selection
Hong Zhang, Dong Lai Hao, Hai Yang Ding · Advanced materials research · 2014
In this Letter, assuming a Nakagami-m fading scenario, closed-form asymptotic expressions for the average symbol error probability (ASEP) of dual-hop amplify-and-forward (AF) cooperative systems with partial relay selection are derived. Based on these expressions, the diversity order is obtained and insightful conclusions are drawn. Numerical results are plotted and the asymptotic curves match very well in the medium and high signal-to-noise ratio (SNR) regions with those obtained by simulations.
