Abstract

The invention concerns a method implemented by computer means for estimating interference on a radiofrequency system using a set of channels (CHi), said interference being caused by interferers of an interfering system using a set of transmission bands (TBi), each of said transmission band extending on a plurality of contiguous channels of said set of channels,Wherein the method comprises:- Determining a set Ω of all possible configurations of occupation or non-occupation of said set of transmission bands, defined as a set of possible vectors= [...,...] satisfying at a time instanta non-overlapping condition of said radiofrequency system, said non-overlapping condition corresponding to the fact that only one interfereramong a set ofpossible interferers, can be active at a same timeon each channel of said set of channels and forming, with contiguous channels, a transmission band,- Obtaining measurements, ...,,of occupation of at least a part of said set of channels, at respective time instants0 <≤wheredefines a given observation time window,- Performing probabilities calculations so as to determine, for each transmission band, an estimated activation rate, on the basis of said measurements...,...,said estimated activation ratecorresponding to an occupation rate of a transmission bandby an interferer within said given observation time window.
