Webfactor in polyphase filters is the Farrow structure [4], which is amenable to time interpo- lation. A digital front-end for direct-sampling receivers is implemented in [12], where WebFirst, I have a fixed sampling rate, then the Farrow filter, then the second sampler, then the TED, Loop filter, NCO and the ouput of the NCO is sent to the second sampler. The TED, loop filter and NCO tends to acquire the symbol frequency. And the Farrow filter allows to sampling to the correct timing with interpolation.
