<p>A receiver apparatus (100) comprises: a frame receiving unit (101) for receiving a radio received frame in which a data signal has been time division multiplexed together with a demodulation reference signal to be used for demodulating the data signal; a fast Fourier transforming unit (102) for transforming the radio received frame of time domain to a received frequency signal of frequency domain (Sf); a data demodulating unit (103) for demodulating the data signal by inversely transforming the received frequency signal to the time domain; a reference signal detecting unit (104) for detecting the demodulation reference signal on the basis of the received frequency signal; and a spectrum analyzing unit (105) for analyzing the frequency spectrum of the received frequency signal when the demodulation reference signal has been detected. In this way, the frequency spectrum can be effectively analyzed.</p> |
