ABSTRACT:
A signal processing system includes a receiving terminal configured to receive a digital signal comprising a plurality of samples associated with a plurality of original sampling times, wherein the original sampling times have a period of T, and a compensation module coupled to the receiving terminal. The compensation module is configured to generate, based on the digital signal, a nominal phase shifted signal having a plurality of nominal phase shifted samples associated with a plurality of phase shifted sampling times, wherein the plurality of phase shifted sampling times correspond to fractional intervals of the original sampling times. The compensation module is further configured to generate a compensated signal based at least in part on the digital signal and the nominal phase shifted signal.
