Abstract:
A method for generating a frequency-modulated signal with high receivability quality, comprising the steps of:before sending an input modulating signal to a modulator, modifying said input modulating signal so as to compensate for distortions which will be introduced in a modulated signal receiving section, wherein the step of modifying said input modulating signal in order to compensate for said distortions comprises the steps of: calculating, starting from said input modulating signal, distortions which will be introduced in said receiving section; and wherein the step of calculating said distortions comprises the steps of: modulating said input modulating signal in a modulator with a useful information signal to be transmitted, so as to obtain a modulated signal; filtering the modulated signal output from said modulator; demodulating the modulated signal after said filtering step; and subtracting the demodulated signal from the input modulating signal, in order to obtain a signal which is representative of said distortions and is suitable to be subtracted from said input modulating signal.
