An apparatus and method for interference alignment and cancellation in a wireless communication system of a multi-user communication environment are provided. The apparatus includes a plurality of receivers, each receiver including a plurality of antennas for receiving signals from a plurality of transmitters. Each of the receivers detects signals of multiple users in a designed order and performs a specific interference alignment on the remaining signals. Also, each of the receivers transmits information about the detected user signal to other receivers to enable the other receivers to cancel the received user signal and perform a user signal detection and a specific interference alignment operation. Accordingly, it is possible to present various types of transmitter/receiver structures that can reduce the complexity while implementing the maximum capacity in an interference environment between a multi-user and single-user TX/RX pair.
