Coverage Probability and Rate for $\kappa-\mu/\eta-\mu$ Fading Channels in Interference-Limited Scenarios

The κ - μ and η - μ are general fading distributions, which model line-of-sight and non-line-of-sight propagation effects, respectively. In this work, expressions for the coverage probability and average rate when the user experiences κ - μ fading with arbitrary values of κ and μ, and interferers experience η - μ fading with arbitrary values of η and μ are derived for downlink of a cellular network. Both expressions can be expressed in terms of sum of Lauricella's function of the fourth kind. Further, using the properties of the special functions, the average rate expression is simplified for various special cases. Finally, simulation results are provided and these match our analytical results.
