Performance Analysis of Fixed Gain Relaying Systems in Nakagami-m Fading Channels

Lei Yang

Abstract

The performance of dual-hop communication systems with fixed gain amplify-and-forward relay is analyzed over non-identical Nakagami-m fading channel.First,Closed-form expressions for outage probability and average symbol error rate(ASER) are derived based on probability density function(PDF) method for the system without cooperative diversity.Then,the expressions for outage probability and ASER and closed-form expression of the n-th moment of received SNR are derived based on moment generating function(MGF) method for the system with cooperative diversity.Simulation results show that,the derived expressions match well with the numerical simulations,and cooperative diversity and larger m values are both of benefit to the improvement of system performance,and the channel quality of the first hop and that of the second hop have different effects on the system performance.
