Summary:A method and apparatus for providing feedback for cancellation of signal impairment in a plurality of separate transmit paths of a transmitter are disclosed. According to one aspect, a method includes receiving a plurality of outbound signals transmitted to the antenna array, the received outbound signals having traversed separate transmit paths of the transmitter. The method also includes converting the plurality of received outbound signals to a corresponding plurality of parallel baseband signals. The corresponding plurality of parallel baseband signals are serialized into a serial feedback signal. L'invention concerne un procédé et un appareil permettant de fournir une rétroaction afin d'annuler une dégradation de signal dans une pluralité de trajets d'émission séparés d'un émetteur. Selon un aspect, un procédé consiste à recevoir une pluralité de signaux sortants transmis au réseau d'antennes, les signaux sortants reçus ayant traversé des trajets d'émission séparés de l'émetteur. Le procédé consiste également à convertir la pluralité de signaux sortants reçus en une pluralité correspondante de signaux de bande de base parallèles. La pluralité correspondante de signaux de bande de base parallèles est sérialisée en un signal de rétroaction en série.
