Outage Performance of Dual-Hop Fixed Gain Amplify-and-Forward Relaying over Nakagami-m Fading with kappa-µ and eta-µ Interference

In this letter, we investigate the outage performance of a dual-hop fixed-gain amplify-and-forward relaying systems in presence of interference at the relay.We assume the desired signal has Nakagami-m fading and the interfering signals experience independent and identically distributed (i.i.d) κ - μ and η - μ fading. We present exact and closed-form expressions for the outage probability. Then we derive closed-form expression for the outage probability when the interfering signals experience i.i.d Nakagami-m fading as the special case of κ-μ and η-μ fading,respectively. Furthermore, the asymptotic outage performance is investigated in high signal-to-interference-noise ratio (SINR). Finally, Monte-Carlo simulation results are given to verify the analytical results.
