Abstract
The present disclosure provides systems and methods for noise tolerant signal processing in a pilot assisted data receiver, including: given received pilots with common pilot components and individual pilot components, computing coefficients associated with the individual pilot components of the received pilots; and applying the computed coefficients to the received pilots to obtain conditioned pilots. The individual pilot components result from relatively slow changes of the received pilots relative to the common pilot components. The common pilot components result from relatively fast changes of the received pilots relative to the individual pilot components.

1-20. (canceled)
A method, in a data receiver, for noise tolerant signal processing, the method comprising:
- receiving an information loaded signal with a co-propagating carrier pilot therewith;
- separating a static component and a dynamic component of the co-propagating carrier pilot;
- averaging the separated static component over a time period, the time period based on polarization evolution dynamics associated with a link coupled to the data receiver;
- and
- re-combining the averaged static component and the dynamic component to provide a noise-reduced carrier pilot.
A processing device, in a data receiver, for noise tolerant signal processing, the processing device comprising:
- circuitry configured to receive an information loaded signal with a co-propagating carrier pilot therewith;
- and
- circuitry configured to a separate static component and a dynamic component of the co-propagating carrier pilot, average the separated static component over a period accommodating for polarization evolution dynamics associated with a link coupled to the data receiver, and re-combine the averaged static component and the dynamic component to provide a noise-reduced carrier pilot.
An optical receiver, comprising:
- components configured to produce a complex electrical signal based on a received information loaded signal with a co-propagating carrier pilot therewith;
- circuitry configured to separate a static component and a dynamic component of the co-propagating carrier pilot, average the separated static component over a period accommodating for polarization evolution dynamics associated with a link coupled to the data receiver, and re-combining the averaged static component and the dynamic component to provide a noise-reduced carrier pilot.
