| description | A DC offset estimator and removal circuit removes the DC offsets for each of the I and Q signal components in a received signal. A gain imbalance estimator and compensator circuit estimates and compensates for gain imbalances within the I and Q signal components. A phase imbalance estimator and compensator circuit estimates and compensates for phase imbalances within the I and Q signal components to produce a communications signal that is compensated for received DC offsets and gain and phase imbalances within the I and Q signal components.
Selon l'invention, un circuit d'estimation et de suppression de décalage de la composante continue supprime les décalages de composante continue pour chacune des composantes de signal I et Q dans un signal reçu. Un circuit d'estimation et de compensation de déséquilibre de gain estime et compense des déséquilibres de gain dans les composantes de signal I et Q. Un circuit d'estimation et de compensation de déséquilibre de phase estime et compense des déséquilibres de phase dans les composantes de signal I et Q afin de produire un signal de communications qui est compensé pour les décalages de composante continue reçus et les déséquilibres de gain et de phase dans les composantes de signal I et Q. |
