Title (EN) METHOD AND SYSTEM FOR COMPENSATING FOR PHASE VARIATIONS CAUSED BY TRANSMITTER ACTIVATION
(FR) PROCEDE ET SYSTEME DESTINES A LA COMPENSATION DES VARIATIONS DE PHASE DUES A L'ACTIVATION DE L'EMETTEUR
Abstract: front page image
(EN)A method and apparatus that reduces the amount of constellation rotation due to power amplifier (PA 125) insertion phase variation during activation (i.e., turn on) of a transmitter (100). This is accomplished by applying an instantaneous phase rotation (175) during the transmitter turn on at digital baseband (165, 170) to counteract and minimize unwanted phase variations.
(FR)L'invention concerne un procédé est un dispositif permettant de réduire le taux de rotation en constellation dû à une variation de phase d'insertion de l'amplificateur de puissance durant la phase d'activation (c'est-à-dire la phase d'allumage) d'un émetteur. Pour ce faire, une rotation de phase instantanée est appliquée lors de l'allumage de l'émetteur à la bande de base numérique pour agir contre et réduire à un minimum les variations de phase non désirées.
