ABSTRACT:
A network device includes a first demodulation path to recover a header portion of a data packet. A second demodulation path recovers a payload portion of the data packet. The second demodulation path includes a down sampler to down sample a payload portion of the data packet. An equalizer equalizes an output of the down sampler. A correlator receives an output of the equalizer. A demodulation controller selects the output of the equalizer or an output of the correlator based on the header portion.
