We investigate the performance of orthogonal frequency division multiplexing (OFDM)-based dual-hop amplify-and-forward (AF) relay networks in the presence of phase noise (PHN). We show that the use of an AF relay may not be beneficial compared to a direct transmission in the presence of PHN. Using outage probability analysis, an upper bound on the allowable PHN level is derived which ensures that...
In this paper, we apply General Order Statistics (GOS) theorem to multi-antenna (MIMO) dual-hop amplify-forward fixed-gain cooperative relay network. General order link, unlike the best one, is selected for the transmission/receiving at each hop. The closed-form expressions of SNR (Signal-to-Noise-Ratio) statistics such as CDF (Cumulative Distribution Function), PDF (Probability Density Function),...
The performance of a dual-hop amplify-and forward relay system is analyzed in terms of outage probability and average symbol error rate. The source-relay and relay-destination channels experience mixed fading distributions namely, Rician and Nakagami-m. Analytical expressions for Cumulative Distribution Function (CDF) and Probability Density Function (PDF) of end-end signal-to-noise-ratio (SNR) are...
