Apparatus and method for neighbor cell interference cancellation in brodaband wireless communication system

The present invention relates to an apparatus and method for canceling interference of a neighboring cell in a wireless communication system. In the terminal device for removing signals of an interference signal received from the at least two receive antennas for receiving a target signal and the neighbor signal from a serving base station and the adjacent base station in a wireless communication system according to the present invention, each of the and a computing unit to a target signal and neighbor signal received from the receiving antenna Fourier transform receives provide Fourier-transformed signals from the computing unit and a channel estimator for estimating a frequency response of each channel received from the serving base station and neighbor base stations, the using the estimated channel frequency response from a received signal; and a detector for detecting a target signal. MIMO, serving cell and neighbor cells, the interference signal removal, the broadband wireless communication system, multiple receive antennas
