A method of demodulating a received signal, computer program product and corresponding device
2016
A method of demodulating a received signal resulting from modulation of a base chirp signal comprising an estimating step (E46) of a symbol carried by the received signal, implementing the following sub-steps: • determining ( E43) of N components making, from said received signal and a reference chirp signal obtained by modulating said base chirp signal by a reference symbol corresponding to a symbol of rank r, an index I decision component , denoted Dl component being a function of a term whose phase depends quadratically of I, with I an integer from 0 to N-1; • decision (E44) of rank k of the symbol carried by said received signal, from the component decision index k, denoted Dk component having a value of extremum among said N decision components.
