METHOD AND APPARATUS OF PROVIDING ADAPTIVE EQUALIZATION USING SIGN PERMUTATION FILTERING

摘要

THE PRESENT INVENTION IS A SYSTEM AND A SYSTEM FOR EQUALIZING A SIGNAL IN A COMMUNICATION SYSTEM. THE SIGNAL IS REPRESENTED BY SAMPLES AT A TIME INSTANT, AND THE SAMPLES ARE FILTERED USING A SIGN PERMUTATION FILTER. AN ESTIMATE OF THE SIGNAL IS DETERMINED BY A LINEAR COMBINATION OF THE SAMPLES WITH CORRESPONDING WEIGHTS. THE ERROR OF THE ESTIMATE IS THEN COMPUTED. THE WEIGHTS ARE UPDATED BY AN UPDATING CIRCUIT TO MINIMIZE THE ERROR.FIG. 2
