<p>PURPOSE: An apparatus and method for calculating a compensation frequency of a carrier frequency offset are provided to calculate a compensation frequency by setting up a compensation frequency output unit. CONSTITUTION: A carrier frequency offset output unit(210) calculates a carrier frequency offset of a first OFDM(Orthogonal Frequency Division Multiplexing) signal which is received from a first transmitter and a carrier frequency offset of a second OFDM signal which is received from a second transmitter. A compensation frequency output unit(220) calculates a frequency corresponding to a spot in which the first carrier frequency offset and the second carrier frequency offset are internally divided in a ratio of a first channel attenuation parameter and a second channel attenuation parameter as a compensation frequency. The first channel attenuation parameter corresponds to a first channel attenuation degree in a channel between the first transmitter and a first receiver. The second channel attenuation parameter corresponds to a second channel attenuation degree in a channel between the second transmitter and a second receiver.
