Abstract
A circuit is configured to receive and process a signal that includes in-phase and out-of-phase components that correspond to in-phase and out-of-phase components of a time sequence of symbols. A phase sensor in the circuit is configured to determine a phase value in accordance with an equalized version of the in-phase component of the signal and the in-phase component of the time sequence of symbols. The phase sensor is further configured to generate an approximation to the out-of-phase component of the signal in accordance with a Hilbert function of order k greater than 1. Terms in the approximation that correspond to future samples of the in-phase component of the signal are replaced with terms that correspond to past samples of an error that corresponds to a difference between samples of the in-phase component of the signal and an output from a detector.
