摘要:
In an OFDM reception apparatus, a Fourier transform unit segments a time-domain signal in an OFDM signal in accordance with a segmenting window signal and converts the time-domain signal into a frequency-domain signal. A first signal extraction unit extracts pilot signals periodically arranged in a frequency direction and in a time direction from an output from the Fourier transform unit. A second signal extraction unit extracts differential reference signals from an output from the Fourier transform unit. A delay profile detection unit performs delay profile detection using the output from the second signal extraction unit, and performs delay profile detection on the output from the first signal extraction unit within a range limited on the basis of a result of the detection. A synchronous reproduction unit generates the segmenting window signal using an output from the delay profile detection unit.
