A phase-noise compensated digital communication receiver (40, 40', 40'') includes a carrier tracking loop (56) which imposes a transport delay on a carrier tracking loop signal (60) before that signal (60) is fed back upon itself. The carrier tracking loop (56) includes a phase rotator (58) that rotates a down-converted digital communication signal (50) by a phase determined by a phase-conveying signal (72). A carrier tracking loop signal is obtained from the carrier tracking loop and delayed in a delay element (82) by a duration that compensates for the transport delay. A phase rotator (84) then rotates the delayed carrier tracking loop signal through a phase value determined by the phase-conveying signal (72) to obtain an open-loop phase signal (86) from which data are extracted. Different embodiments of the receiver (40, 40', 40'') are provided to accommodate adaptive equalizer (54) issues.
