ABSTRACT:
An OFDM transmitter includes, a data signal generator which generates a data signal by modulating a bit string obtained by channel coding, a pilot signal generator which generates a pilot signal, an allocation unit which allocates the pilot signal and data signal to a pilot subcarrier and a data subcarrier, a multiplier which multiples the first pilot signal and the first data signal by complex numbers for subcarrier group formed of specific pilot subcarrier of the pilot subcarriers and specific data subcarrier of the data subcarriers, a modulator which performs OFDM modulation on the second pilot signal and the second data signal to generate an OFDM signal, and a transmitting unit which transmits the OFDM signal.
