Digital broadcasting receiving apparatus with channel estimation function

Abstract

A delay profile generating circuitgenerates a delay profile signal. Concerning the delay profile signal, a ghost decision circuitmakes a decision as to the presence or absence of ghosts that will appear during traveling of a mobile vehicle in response to a transmission mode signal fed from a changeover switch. The delay profile signal and the decision signal about the presence/absence of the ghosts are delivered to a window control circuitvia an accumulator. The window control circuitsets and controls the FFT window position of an FFT circuitin response to a guard correlation signal fed from a guard correlation signal generating circuitand a signal fed from the accumulator
