A Digitalized Automatic Ghost Cancerller

Abstract

Among various approaches for realizing a practical ghost canceller, the one based on an adaptive transversal filter has recently been studied most enthusiastically.(1) ~(3) The inherent merit of this approach lies in the fact that it can cancel diffused multiple ghosts, generated by complex transmission path irregularities. This feature can not be attained by a single-delay-line ghost canceller.
