The present invention relates to a receiving device and method for removing a mismatch in a wireless communication system, and to a low noise amplifier (LNA) therefor. According to the present invention, the receiving method for removing the mismatch comprises the steps of: distinguishing the type of input signal received through a wireless network; controlling such that a common bias is applied to transistors within a low noise amplifier, if said input signal is a wideband signal; and outputting a signal from which said mismatch has been removed, by using a current mirror mode in which current paths within said low noise amplifier are crossed.

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.
