Abstract
In accordance with an embodiment of the disclosure, systems and methods are provided for aligning signals in a timing recovery system. In certain implementations, a coarse phase error indicative of a phase offset between a reference signal and a signal is identified. The signal is transformed based at least in part on the coarse phase error, and operation of a phase-locked loop is initiated based at least in part on the coarse phase error.
Claims22
A method for aligning signals in a timing recovery system, comprising:
- identifying a coarse phase error indicative of a phase offset between a reference signal and a signal by iteratively selecting a candidate phase offset in a plurality of candidate phase offsets, wherein the coarse phase error is identified as the candidate phase offset corresponding to an error below a predetermined threshold;
- transforming the signal based at least in part on the coarse phase error;
- and
- initiating operation of a phase-locked loop based at least in part on the coarse phase error.

A timing recovery apparatus for aligning signals, comprising:
- an identifier configured to identify a coarse phase error indicative of a phase offset between a reference signal and a signal by iteratively selecting a candidate phase offset in a plurality of candidate phase offsets, wherein the coarse phase error is identified as the candidate phase offset corresponding to an error below a predetermined threshold;
- a transformer configured to transform the signal based at least in part on the coarse phase error and
- a phase-locked loop for aligning a transformed version of the signal to the reference signal.
