DIGITAL BROADCAST RECEIVING APPARATUS HAVING TRANSMISSION PATH ESTIMATING ABILITY

摘要

A delay profile generating circuit (9) generates a delay profile signal. For this delay profile signal, a ghost determining circuit (10) determines, based on a transmission mode signal from a switch (8), whether any ghosts are present or absent during a movement of a mobile vehicle. The ghost determining circuit (10) then sends the delay profile signal and the ghost presence/absence determination signal to a window control circuit (13) via a storage part (11). The window control circuit (13) establishes and controls an FFT window position of an FFT circuit (5) in accordance with both a guard correlation signal from a guard correlation signal generating circuit (12) and the signals from the storage part (11).
