摘要： A delay profile generating circuit 9 generates a delay profile signal. Concerning the delay profile signal, a ghost decision circuit 10 makes 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 8. The delay profile signal and the decision signal about the presence/absence of the ghosts are delivered to a window control circuit 13 via an accumulator 11. The window control circuit 13 sets and controls the FFT window position of an FFT circuit 5 in response to a guard correlation signal fed from a guard correlation signal generating circuit 12 and a signal fed from the accumulator 11.
