Zusammenfassung:	PURPOSE: An adaptive equalizer and a method thereof for phase noise removal in an OFDM(Orthogonal Frequency Division Multiplexing) communication system are provided to increase computational efficiency by removing a CPE(Common Phase Error) and an ICI(InterCarrier Interference) when transmitting a signal. CONSTITUTION: A matching filter unit(110) performs convolution of a reception signal and an equalizer coefficient. The matching filter unit outputs an estimation transmission signal. An equalizer coefficient update unit(140) updates the equalizer coefficient by using error and reception signal of the estimation transmission signal. The equalizer coefficient update unit supplies the updated equalizer coefficient to the matching filter unit.
