Abstract
A time from the start of a reception operation to the output of video, audio or the like is shortened. An OFDM reception apparatus is provided for receiving an OFDM signal composed of a plurality of carriers, comprising a fast Fourier transform section for converting a received time-domain OFDM signal into a frequency-domain OFDM signal, an equalization section for performing waveform equalization with respect to the frequency-domain OFDM signal, and outputting the waveform-equalized OFDM signal, and a modulation scheme estimating section for estimating a modulation scheme for a plurality of carriers constituting the waveform-equalized OFDM signal based on signal points of the plurality of carriers, and outputting an obtained estimation result. The OFDM reception apparatus performs a process for obtaining transmitted information with respect to the received OFDM signal, depending on the estimation result.
