“…Besides, bounds on the secrecy outage probability for secure communications under dependent fading channels were obtained in [10]. Copulas have also been used for analyzing the impact of interference correlation in the context of ad hoc networks [11]. Finally, the authors in [12] derived closed-form expressions for the outage probability and the coverage region in the correlated Rayleigh fading clean MAC, bringing out the negative effect of a positive dependence between fading channels in the system performance.…”

We investigate the impact of fading correlation on the performance of the doubly dirty fading multiple access channel (MAC) with non-causally known side information at transmitters. Using Copula theory, we derive closed-form expressions for the outage probability and the coverage region under arbitrary dependence conditions. We show that a positive dependence structure between the fading channel coefficients is beneficial for the system performance, as it improves the outage probability and extends the coverage region compared to the case of independent fading. Conversely, a negative dependence structure has a detrimental effect on both performance metrics.
