Abstract
An apparatus and method for providing timing recovery under conditions of low signal to noise ratios (SNRs) is disclosed herein. A preliminary phase error signal is generated by comparing an input signal with a preliminary estimation of an output signal corresponding to the input signal. A correction signal is generated as a function of the output signal, input signal, and preliminary phase error signal. The preliminary phase error signal and the correction signal are combined to generate a final phase error signal.
