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