Method, Computer Program, Device And Radiofrequency System For Estimating Interference On A Radiofrequency System Using A Set Of Channels

Abstract: The invention relates to a method 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. The method comprises: - Determining a set of all possible configurations of occupation or non- occupation of said set of transmission bands, defined as a set of possible vectors, - Building a matrix from a stacking of all the possible vectors, - Obtaining measurements of occupation of at least a part of said set of channels, at respective time instants, - Computing probabilities using a channel transition function so as to determine, for each transmission band, an estimated activation rate, on the basis of said measurements, said estimated activation rate corresponding to an occupation rate of a transmission band by an interferer within said given observation time window, and the probabilities computations comprise an iterative resolution of a non-linear optimization problem with a constraint derived from the Gibbs' inequality.
