An OFDM receiver (100) has an FFT circuit (107c), an OFDM demodulating section (107) which performs OFDM demodulation for the received OFDM signal, a D/U (Desire to Undesire ratio) measuring section (106a) which measures the D/U in accordance with the OFDM-demodulated signal, a window function processing section (107b) provided at the preceding stage of the FFT circuit (107c), and a selecting section (106b) which switches the factors of the window function processing section (107b) in accordance with the D/U measured by the D/U measuring section (106a). This ensures elimination of interfering waves excellently with relatively simple configuration and low power consumption while suppressing deterioration in the BER due to processing of the window function.
