An interference canceller () includes an interference cancellation coefficient calculator () configured to calculate an interference cancellation coefficient using a received value located in a location of a reference signal (RS) from a channel estimate H calculated by a channel estimator and a received signal r delivered from an FFT, an interference cancellation filter () configured to cancel interference in the received signal and the channel estimate using the calculated interference cancellation coefficient, an increment or decrement operator () configured to increase or decrease the received signal and the channel estimate by &#x3bb; times; an interference cancellation output controller () configured to receive a channel estimate before interference cancellation and a channel estimate after interference cancellation to compare a signal before the interference cancellation with a signal after the interference cancellation and then determine whether to deliver the signal before applying the interference cancellation or the signal after applying the interference cancellation, and a switch () configured to receive a control signal from the interference cancellation output controller ().
