The analysis considers a general distance-based path loss with Rayleigh and Rician fading channels and a sectored antenna model. Moreover, the nodes are uniformly distributed over a circular or annular area centered at the receiver. The main contribution of the paper is the derivation of the moment generating function (MGF) of the aggregate interference power. The MGF is adopted in a moment-based approximation to a Gamma distribution and used as a model of the aggregate interference power. Several simulations confirm the effectiveness of the proposed approximation for different scenarios, highlighting the effect of directional communications on the aggregate interference power.654205engAggregate InterferenceDirectional BeamformingMillimeter-Wave CommunicationsPerformance AnalysisStochastic Geometry ModelingComputer Science ApplicationsElectrical and Electronic EngineeringApplied Mathematicsconference object10.1109/VTC2021-Spring51267.2021.9448808https://www.scopus.com/pages/publications/85112423730
