1. A method for improving the ability of a data slicer to properly resolve data bits of a received message in the presence of high noise levels relative to the received message, the received message also exhibiting signal fading, the data slicer including a first input, a second input and an output, the method comprising the steps of:

  • providing a peak detector that includes a peak detector input and a peak detector output, wherein the peak detector input is coupled to the first input of the data slicer, and wherein the peak detector output provides a peak detector signal that corresponds to a peak of a received demodulated signal; and

    providing a peak detector signal filter coupled between the peak detector output and the second input of the data slicer, wherein the peak detector signal filter is configured to substantially prevent impulse noise from increasing a variable data slicer threshold on the second input of the data slicer while simultaneously allowing the data slicer threshold to substantially follow the variations in the demodulated signal attributable to signal fading.
