Zusammenfassung:Embodiments are disclosed for timing recovery used in conjunction with a phase detector embedded in a receiver of a communication system. An example method includes receiving, via a receiver of a communication system, an input signal. The input signal encodes a plurality of bits in a number of amplitude levels. The method further includes using an analog to digital converter to generate a sampled signal based on the input signal. The method further includes using a first interpolation filter to filter the sampled signal. The method further includes using a second interpolation filter to filter the sampled signal. The method further includes using a first non-linear device to process an output of the first interpolation filter. The method further includes using a second non-linear device to process an output of the second interpolation filter. The method further includes performing a mathematical operation on an output of the first non-linear device with an output of the second non-linear device to generate phase information.
