Title: Richard Buz: Innovator in Adaptive Decision Feedback Equalization
Introduction
Richard Buz is a notable inventor based in Rohnert Park, CA (US). He holds a total of 5 patents that contribute significantly to the field of adaptive decision feedback equalization. His work focuses on enhancing the performance of equalizers used in communication systems.
Latest Patents
One of his latest patents is titled "Clustering blind convergence process in an adaptive decision feedback equalizer." This invention introduces a blind convergence process that utilizes a quadrature amplitude modulation (QAM) slicer. The process involves initializing forward and feedback tap coefficients with predetermined values and operates in two modes: clustering mode and decision-directed mode. This innovation allows for blind convergence of an equalizer across a wide range of QAM indexes, enhancing the efficiency of communication systems.
Another significant patent is the "Method of detection of misconvergence using constellation scanning in an equalizer." This method detects misconvergence in an equalizer by processing random symbols through the equalizer and quantizing them into a constellation map. By analyzing the number of non-zero signal counters, the method determines whether the equalizer has converged, providing a reliable means of ensuring optimal performance.
