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.
