Partially disjoint equalization and carrier recovery

An apparatus in a signal receiver for providing feedback to an adaptive equalizer of the signal receiver, the apparatus comprising:

• an initial carrier recovery component configured to generate a carrier recovery output based on equalized output received from the adaptive equalizer and an estimate of frequency components of a received signal;
• a phase rotation and detection component configured to receive the equalized output from the adaptive equalizer and to detect symbols carried in the received signal based on the equalized output following a phase rotation performed on the equalized output, the phase rotation performed based on the carrier recovery output generated by the initial carrier recovery component, the phase rotation and detection component configured to provide the detected symbols for feedback directly or indirectly to the adaptive equalizer;
• and
• a fine carrier recovery component separate from the initial carrier recovery component and the phase rotation and detection component, wherein the phase rotation and detection component is configured to provide the equalized output following the phase rotation as symbol input to the fine carrier recovery component.
