<p>The present invention is to provide an interference alignment and cancellation apparatus and a method therefor for using in a wireless communication system in a multi-user communication environment. According to one embodiment of the present invention, an interference alignment and cancellation apparatus has a plurality of antenna and includes receivers for receiving a signal transmitted from a plurality of transmitters through the antenna. The respective receivers detects signals from many users according to a designed order and interference-aligns the remaining signals in the process of detection. Also, the respective receivers make detection and interference alignment operation of a user signal after the other receivers cancel the transmitted user signal by transmitting information for the detected user signal to the other receivers. In the present invention, various types of transceiver structure which is capable of achieving the maximum capacity and reducing the complexity under the interference between multi-user and single-user transceiving pairs.
