Abstract
The steps and corresponding structures include: extracting at least K+N pieces of data corresponding to one symbol including a guard interval from a frequency-transformed received signal to generate 2N pieces of data, as expanded time axis data, by adding zero before and after the extracted data; shaping, by utilizing a window shaping part, a waveform by multiplying the expanded time axis data by a window coefficient; performing DFT (discrete Fourier transform), by utilizing a DFT part, with respect to output of the window shaping part; performing a demodulation of a sub-carrier by extracting a sub-carrier component; calculating an inter-carrier interference component from output of the DFT part; and selecting a window coefficient based on the inter-carrier interference component to output to the window shaping part.
