在本文中，我们研究了在发射机侧信息（SI）存在和不存在的情况下，相关衰落对无线多址信道（MAC）性能的影响，其中衰落系数根据Fisher-Snedecor <inline-formula>< text -math符号="LaTeX">$mathcal {F}$</ text -math></inline-formula>分布建模。具体来说，我们表示了两种情况：（<inline-formula>< text -math符号="LaTeX">$i$</ text -math></inline-formula>）干净MAC（即，在发送器处没有SI）， （<inline-formula>< text -math符号="LaTeX">$ii$</ text -math></inline-formula>）双脏MAC（即，在发送器处具有非因果已知的SI）。对于这两种系统模型，我们导出了独立衰落条件下的停电概率（OP）和平均容量（AC）的封闭表达式。此外，利用copula理论，我们得到了两种模型在正相关衰落条件下的OP和AC的精确解析表达式。最后，用数值方法验证了分析结果的有效性。
In this article, 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 <inline-formula><tex-math notation="LaTeX">$mathcal {F}$</tex-math></inline-formula> distribution. Specifically, we represent two scenarios: (<inline-formula><tex-math notation="LaTeX">$i$</tex-math></inline-formula>) clean MAC (i.e, without SI at transmitters), (<inline-formula><tex-math notation="LaTeX">$ii$</tex-math></inline-formula>) doubly dirty MAC (i.e., with the non-causally known SI at transmitters). For both system models, we derive the closed-form expressions of the outage probability (OP) as well as the average capacity (AC) under independent fading conditions. Besides, exploiting copula theory, we obtain the exact analytical expressions for the OP and the AC under positive dependence fading conditions in both considered models. Finally, the validity of the analytical results is illustrated numerically.
