Abstract

This invention discloses a method for low-Earth orbit (LEO) satellite interference modeling and performance analysis based on beam hopping, relating to the field of LEO satellite communication technology. The method includes: S1) establishing a LEO satellite downlink communication scenario and setting cell layout scenario parameters within the coverage area; S2) calculating path loss and channel distribution under fading based on the cell layout scenario parameters; S3) designing a periodically polled beam hopping time schedule and selecting random beam hopping and non-beam hopping time schedules as comparison schemes for interference analysis; S4) establishing a beam hopping-based LEO satellite interference model based on path loss, fading channel distribution, and the beam hopping time schedule, and simulating and comparing inter-beam interference and system performance under periodically polled beam hopping, random beam hopping, and non-beam hopping time schedules. The beam hopping-based LEO satellite interference model of this invention can be used for performance simulation analysis of beam hopping satellite communication networks and provides theoretical and technical support for system design.
