Abstract
A method for generating a pulse-position-modulated signal. The signal includes a temporal succession of waveforms among Ns waveforms obtained by time shift that is an integer multiple of an elementary time duration Tc. The method includes the following steps executed for a k rank symbol among Ns symbols: obtaining, a set of N modulation coefficients c, a modulation coefficient of index n, c, being expressed as the product of a reference modulation coefficient ccoming from the Fourier series decomposition of a reference waveform associated with a symbol of rank r multiplied by a phase shift term the argument of which is proportional to n; and generating M temporal samples of a k-th waveform carrying the symbol of rank k by Fourier transformation of said set of N modulation coefficients c.
