Abstract
Provided are an apparatus and a method for removing an interference in a multiple antenna system. The apparatus includes a channel estimator, a covariance matrix generator, a weight calculator, and a beam forming unit. The channel estimator estimates a channel for a service cell and an interference channel for an adjacent cell using sounding signals via a plurality of antennas. The covariance matrix generator generates a covariance matrix as an average value from the interference channel. The weight calculator calculates a beam coefficient using the covariance matrix. The beam forming unit forms a beam using the beam coefficient.
