Abstract
Provided are an apparatus and method for canceling interference in a Broadband Wireless Access (BWA) system. The method includes estimating channel coefficient vectors of a plurality of Mobile Stations (MSs) using the same resource; computing a correlation matrix by subtracting a channel coefficient vector of a corresponding MS from a specific tone input vector within the same resource and by auto-correlating the subtracted vector; canceling interference from the data-tone input vector and the channel matrix by using the correlation matrix; and estimating a transmission symbol for each MS by performing Multiple Input Multiple Output (MIMO) detection by using the interference-cancelled input vector and the interference-cancelled channel matrix.
