Abstract
A method for demodulating a received signal resulting from the modulation of a basic chirp signal including estimating of a symbol carried by the received signal, implementing the following sub-steps: determining N decision components from the received signal and from a reference chirp signal obtained by modulating the basic chirp signal by a reference symbol corresponding to a symbol of rank r, a decision component of index I, denoted as a component Dl, being a function of a term, the phase of which depends quadratically on I, with I being an integer from 0 to N−1; and deciding the rank {circumflex over (k)} of the symbol carried by the received signal, from the decision component, of index k, denoted as a component Dk, having an extremum value among the N decision components.
