ABSTRACT:
A block diagram and concept approach for use in conjunction in decision feedback equalization of providing positive decision feedback to enhance the amplitude of the present bit at the same time as delayed intersymbol interference feedback is provided to provide a larger eye pattern in the compensated and equalized output signal as compared to that obtained without the positive decision feedback pulse amplitude enhancement.
