ABSTRACT:
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.
