An Approximation of the Outage Probability for Multi-hop AF Fixed Gain Relay (0812.0904v1)
Published 4 Dec 2008 in cs.PF
Abstract: In this letter, we present a closed-form approximation of the outage probability for the multi-hop amplify-and-forward (AF) relaying systems with fixed gain in Rayleigh fading channel. The approximation is derived from the outage event for each hop. The simulation results show the tightness of the proposed approximation in low and high signal-to-noise ratio (SNR) region.
