Abstract (en)
[origin: WO2020260177A1] The invention relates to a method for generating a signal comprising a succession of modulated chirps over time. The modulation corresponds to a circular permutation of the pattern of variation of the instantaneous frequency of a basic chirp over the symbol time Ts, the permutation being obtained by a time shift of s times an elementary time duration Te, such that M*Tc=Ts. Such a method comprises, for the generation of a given chirp in the succession of chirps over time: - differential encoding (E200) between, on the one hand, a modulation symbol associated with a chirp preceding the given chirp in the succession of chirps over time and, on the other hand, a given information symbol of the constellation of M symbols, the differential encoding delivering a given modulation symbol; and - modulation (E210) of the basic chirp according to the given modulation symbol generating the given chirp.
