A receiver includes a first mixer configured to provide an in-phase (I) component of a radio frequency (RF) signal to an I channel by down-converting the RF signal, a second mixer configured to provide a quadrature (Q) component of the RF signal to a Q channel by down-converting the RF signal, amplification means, arranged on the I and Q channels, configured to amplify the I and Q components, a mismatch estimator configured to convert the amplified I and Q components into a frequency domain, and estimate a gain mismatch value and a phase mismatch value on the basis of the converted components, and a mismatch compensator configured to compensate for mismatch of the received signal on the basis of the estimated gain and phase mismatch values.
