Abstract
A receiving apparatus for receiving a downlink signal in which pilot symbols are mapped discontinuously, includes: a unit configured to extract reference signals from the downlink signal that is Fourier transformed by a Fourier transform unit; a unit configured to generate a first signal having a first window size by arranging the extracted reference signals on the frequency axis and by performing inverse Fourier transform on the reference signals; a unit configured to divide the first signal into a plurality of signals to extract a signal included in a second window; a unit configured to generate a second signal that includes the signal included in the second window and that has a window size similar to the first window size; a Fourier transform unit configured to generate a third signal from the second signal; and a unit configured to calculate received power based on the third signal.
