Abstract
Disclosed is a method for canceling multi-user interference (MUI) by a base station (BS) in a wireless communication system. The method includes determining the number of tones to accumulate channel values among tones included in a resource area, based on a minimum delta cyclic shift (CS) that represents a minimum gap between CS values allocated to user equipments (UEs) and a number of UEs to be multiplexed, creating a matrix of amounts of change in phase for the tones to accumulate for the UEs to be multiplexed, and canceling MUI based on a signal matrix.
