Abstract:
1. A mobile station for receiving a target signal and a neighbor signal through at least two receiving antennas from a serving base station and neighbor base stations, and canceling the neighbor signal from among the received signals so as to cancel a neighbor cell interference in a wireless communication system, the mobile station comprising: an operator for performing a Fourier transform operation with respect to the target signal and neighbor signal received through each of the receiving antennas; a channel estimator for receiving the Fourier-transformed signals from the operator, and estimating a frequency response of each channel received from the serving base station and neighbor base station; and a detector for detecting a target signal defined by a following Equation from the received signals by using the estimated channel frequency response, wherein CSI refers to channel state information defined by a following Equation, r
