Aggregate interference from HAPS into FWA systems: A probabilistic approach

This paper presents a probabilistic model to assess the interference produced by HAPS systems into FWA systems operating in the same frequency bands. To avoid some of the conservative assumptions considered in the traditional interference evaluation methods, in the proposed probabilistic approach the sidelobe antenna gains are characterized by random variables. Minimum operating distances between FWA receivers and HAPS systems are defined and evaluated using the proposed probabilistic model, for some specific interfering scenarios. Results are compared to those obtained with the usual deterministic approach.
