Abstract
A method for estimating parameters of a single signal or mixed-frequency signals in a given frequency band comprises: receiving the signal(s); calculating a spectral correlation function having variables f and α (cyclic frequency) for different values of L taken from a set of q strictly positive values, where, for each q, α can independently take on one or more discrete values and/or cover one or more value ranges; from each calculation, extracting a set of local maxima detected on the basis of the variables f and α or on the basis of variable f for each discrete value of α, each of said peaks being characterized by a triplet [LApi, LFpi, Lαpi], LFpi and Lαpi being the frequency and cyclic frequency of said triplet, respectively, and LApi being the amplitude; and identifying groups of triplets as being the signature left by a set of parameters making up the signal(s).
