Abstract: An interference alignment method using multiple antennas in a multi-cell overlapped environment, includes: when at least one transmission and reception ends having at least one or more antennas communicate with each other, establishing at least one or more channels from the transmission end to the reception end. Further, the interference alignment method includes designing a processing filter for a transmission signal transmitted from the transmission end to the reception ends; and designing a processing filter for a reception signal that is received by the reception end.

Abstract: Disclosed is a method for removing signal interference in a MIMO-based interference removing apparatus including transmitting a reference signal to at least one receiver; if channel information is estimated by the receiver, receiving the estimated channel information from the receiver as a feedback signal; and producing transmission pre-coding matrix, beam forming matrix, and weighted matrix using the received channel information. Further, the method includes transmitting information containing the transmission pre-coding matrix, the beam forming matrix, and the weighted matrix by including them in a pilot signal to the receiver, and the MIMO-based interference removing apparatus comprises at least one transmitter.
