ABSTRACT:
A data recovery algorithm for implementation in a radio transmitter or receiver that includes a direct current level setting circuit with a preamble detector which will establish a threshold for a simplified decision simplified equalizer slicer that improves receiver performance in a feedback manner by utilizing an analog comparator, a one symbol long one bit resolution delay line and a summing junction.
