In this paper, we investigate the impact of correlated fading on the performance of wireless multiple access channels (MAC) in the presence and absence of side information (SI) at transmitters, where the fading coefficients are modeled according to the Fisher-Snedecor F distribution. Specifically, we represent two scenarios: (i) clean MAC (i.e, without SI at transmitters), (ii) doubly dirty MAC (i.e., with the non-causally known SI at transmitters). For both system models, we derive the closed-form expressions for the outage probability (OP) in independent fading conditions. Besides, exploiting copula theory, we obtain exact analytical expressions for the OP under the positive dependence fading conditions in both considered models. Finally, the validity of the analytical results is illustrated numerically.
