Abstract
A burst error limiting symbol detector system includes a symbol detector circuit responsive to a corrected sample signal for detecting multilevel or multidimensional symbols encoded in the corrected sample signal with reference to a plurality of associated thresholds. A feedback equalizer circuit provides a feedback equalizer signal for cancelling undesired distortion in an input signal. A summing circuit is responsive to the input signal and the feedback equalizer signal to provide the corrected sample signal to the symbol detector circuit. A feedback modification circuit is responsive to the corrected sample being within one of a plurality of valid symbol windows to feed back the detected symbol to the feedback equalizer and is responsive to the corrected sample being within one of plurality of marginal threshold windows to feed back a corresponding intermediate value to the feedback equalizer.
