This letter considers the multiuser amplify-and-forward relay network, which includes the source-to-destination links. We derive an approximate expression in closed-form for the exact outage probability in Rayleigh fading channels. In the high signal-to-noise ratio regime, we derive a simple expression to approximate the asymptotic outage probability and analyze the diversity performance. The analysis...
This paper analyzes the performance measures of amplify-and-forward (AF) relaying over non-identical Nakagami-m fading channel. The exact probability density functions (PDFs) of total signal-to-noise ratio (SNR) for variable gain relaying and fixed gain relaying are deduced, and the theoretical formulas of moment generating function (MGF) and moments for fixed gain relaying are presented. Since the...
This paper provides three channel estimations including LS (least square) estimation, LMMSE (linear minimum mean square error) estimation and Lr-MMSE (low rank minimum mean square error) estimation utilized to the relay channel to approximate the optimal solution in OFDM system. The simulation results show that LMMSE estimation outperforms the other two estimations, but it is too complicated. The...
