Popis:	This paper aims at investigating the impact of interference on the performance of a wireless communication system operating over the Fisher–Snedecor $$\mathcal {F}$$ composite fading channel. In particular, we consider an interference-limited network scenario, where both links: the main link and interfere links, are modeled by $$\mathcal {F}$$ fading channels. Then, closed-form expressions for the probability density function (PDF) and cumulative distribution function (CDF) are derived for such scenario. Based on the obtained PDF and CDF, closed-form expressions for the outage probability, average bit error rates (BERs) for several modulation schemes, and average channel capacity are derived. Furthermore, we derive the expressions for the asymptotic performance for these above-mentioned metrics in order to provide more insights into the impact of different channel parameters on the system performance. To provide further insights into the impact of interference, the expressions for the performance metrics under the no-interference setup have been also derived and compared to its interference-limited counterparts. The excellent agreement between the analytical and Monte-Carlo simulations validates our analysis.
