METHOD FOR TRANSMITTING OFDM SIGNAL, OFDM TRANSMITTER AND OFDM RECEIVER

摘要

PPROBLEM TO BE SOLVED: To provide the method for transmitting an OFDM signal which can reduce the calculation amount when a macro diversity reception is performed at a receiver side, can reduce degradation in a channel estimation accuracy caused by an interference and can be easily controlled. PSOLUTION: A subcarrier group including a plurality of sucarriers is set. After multiplying a pilot signal assigned to the subcarrier in the subcarrier group and a data signal by a complex number value that is determined for each subcarrier group, an OFDM modulation is performed to produce an OFDM signal and the OFDM signal is transmitted.
