Abstract
A method and corresponding device for processing a frequency-modulated analog signal are disclosed. The signal includes a number of symbols belonging to a set of M symbols respectively associated with at least one frequency of a set of M frequencies. The method includes a phase of reading each symbol of the signal that includes a sampling of a signal portion corresponding to the duration of a symbol and delivering N samples (M being less than N). M individual discrete Fourier transform processing operations are performed on the N samples. Each individual processing operation is associated with each of the frequencies. The M individual processing operations deliver M processing results. The value of the symbol can be determined from the M processing results.
