1. A communication method in which a plurality of different terminals performs communication using OFDM signals at the same time, wherein a transmitting terminal allocates minimum transmission power for transmission to a specific subcarrier mutually known between the transmitting terminal and a receiving terminal within a communication slot, which is a frequency band in units of access, and the receiving terminal performs frequency conversion of a received signal assuming that a frequency of said specific subcarrier corresponds to a direct current potential and converts the frequency-converted received signal to a digital signal by using an analog to digital converter for data demodulation.
