Abstract: The present invention includes a process of correcting the phase offset of a reception signal received through an antenna, for each of M cells, and performing channel estimation on each of the M cells with regard to the reception signal of which the phase offset is corrected, a process of correcting an inter-cell timing offset in a channel estimation value obtained by performing the channel estimation on each of the M cells, and regenerating the interference element of a reference signal by using the corrected channel estimation value, a process of regenerating the phase offset difference between each interference cell and a serving cell, and adding the same to the interference element of the reference signal, a process of removing the interference element of the reference signal with the added offset difference in the reception signal, and a process of equalizing the reception signal, from which the interference element is removed, by using a predetermined filter coefficient.
