Patent ID: 8582691

Claim:
A receiving apparatus configured to receive a downlink signal in which pilot symbols are mapped discontinuously on a frequency axis and on a time axis, comprising: a first Fourier transform unit configured to perform Fourier transform on the downlink signal; an extraction unit configured to extract reference signals included in a predetermined band from the downlink signal that is Fourier transformed by the first Fourier transform unit; an inverse Fourier transform unit configured to generate a first signal having a first window size by arranging the reference signals, extracted by the extraction unit, on the frequency axis and by performing inverse Fourier transform on the reference signals arranged on the frequency axis; a time extraction unit configured to divide the first signal into a plurality of signals to extract a signal included in a second window; an adjustment 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 second Fourier transform unit configured to generate a third signal by performing Fourier transform on the second signal; and a radio quality calculation unit configured to calculate received power based on the third signal.
