Abstract
In one aspect, the disclosure relates to a method of clock recovery. The method includes sampling one or more signals at a symbol rate to generate a set of samples; zero-padding one or more samples in the set of samples; filtering one or more zero-padded signals with a filter to generate a set of filtered samples; and modifying the set of filtered samples by applying a non-linear operator to generate an output comprising a spectral correlation.
