Patent ID: 8737534

Claim:
A receiver having Inphase-Quadrature (I-Q) imbalance compensation, comprising: a calculation unit, being configured to execute the following operations: calculating a first ratio of a first ideal conjugate receiving mirror to a first ideal receiving value of a first receiving signal, the first receiving signal having a frequency; calculating a second ratio of a second ideal conjugate receiving mirror to a second ideal receiving value of a second receiving signal, the second receiving signal having the frequency; calculating a cross-ratio parameter, the cross-ratio parameter being a third ratio of the first ratio to the second ratio, the third ratio being a value, the value being unequal to zero and one; and calculating an I-Q imbalance compensation parameter according to the cross-ratio parameter, the first ideal receiving value, the first ideal conjugate receiving mirror, the second ideal receiving value, the second ideal conjugate receiving mirror, the first receiving signal and the second receiving signal; and a compensation unit, being electrically connected to the calculation unit and configured to compensate a third receiving signal according to the I-Q imbalance compensation parameter, the third receiving signal having the frequency.
