A receiver comprises a carrier tracking loop (CTL), a filter, a look-up table and a rotator The CTL provides a base-band signal having in-phase and quadrature signal components. The filter provides a DC-offset level associated with each component to the look-up table, which, in response thereto, provides a phase adjustment signal to the rotator The latter then rotates the baseband signal as a function of the phase adjustment signal for correcting for carrier phase ambiguity.
