A Fourier transform is applied (205) to a received multiple-carrier phase- modulated signal. The output of the transform includes real and imaginary elements that are associated with the multiple carriers. These elements are processed to provide a magnitude (209) and a sign (211) for the quadrature, Q, and in-phase, I, components of the desired signal. Q and I are processed (213) to yield the desired output signal that approximates the originally obtained signals that were phase-modulated and transmitted on the multiple carriers.

On applique (205) une transformée de Fourier à un signal modulé en phase transmis sur plusieurs porteuses. Le résultat de la transformée comporte des éléments réels et imaginaires associés aux différentes porteuses qui sont traités pour attribuer une grandeur (209) et un signe (211) aux composants en quadrature, Q, et en phase, I, du signal désiré. Q et I (213) sont ensuite traités pour donner le signal résultant désiré très proche du signal original modulé en phase transmis sur plusieurs porteuses.
