摘要： An apparatus and a method for interference cancellation in a Multiple Input Multiple Output (MIMO) wireless communication system. The method for interference cancellation includes equalizing first reception signals received through two or more reception antennas to estimate transmission signals transmitted through two or more transmission antennas, generating two or more second reception signals in which a mutual interference between the transmission signals is removed from the first reception signals by using the estimated transmission signals, independently equalizing the generated two or more second reception signals, and combining the independently equalized two or more second reception signals to estimate a transmission signal in which an interference is removed.

摘要： A method for receiving a signal using an equalizer receiver in a mobile communication system includes matched-filtering a signal received via an antenna. The method also includes generating different phase information for a serving cell and one or more other cells. The method further includes generating Pseudo-random Noise (PN) codes for the cells based on the phase information; estimating channel estimation values for the cells using the PN codes and the filtered signal; modeling random sequences similar in statistical property to signals transmitted from the cells using the channel estimation values, and generating a filter coefficient using the modeled random sequences; and equalizing the filtered signal using the filter coefficient. By doing so, the receiver's channel estimation performance and equalizer adaptation performance may be maximized.
