PURPOSE:To attain miniaturization by reducing the circuit scale of a demodulator receiving and detecting a multi-phase modulated wave obtained by multiplexing transmission data by plural carrier waves. CONSTITUTION:A received input (i) is separated into the I and Q signals of the respective carrier waves by FFT 11 and an reverse FFT 12 generates a synthetic I and Q signals. Then, one equalizer 13 equalizes the received input by setting the I and Q signals resynthesized from demodulation data by reverse FFT 16 to be a reference signal. Thereby, equalization is attained by one equalizer without regard to the number of the carrier waves so as to reduce the circuit scale. |
