Title (EN) COMMUNICATION SYSTEM WITH END-TO-END QUADRATURE BALANCE CONTROL
(FR) SYSTEME DE COMMUNICATIONS A COMMANDE D'EQUILIBRE DE PHASE EN QUADRATURE DE BOUT EN BOUT
Abstract: front page image
(EN)A communication system (10) includes a transmitter (20) having programmable signals (46, 58, 60, 80) which can be used to adjust transmitter-caused quadrature-phase signal imbalances. A receiver (18) of the system (10) is remotely located from the transmitter (20) and generates a signal quality statistic (102, 112) that is monitored in a slow-tracking feedback loop to formulate commands which indicate how to program the programmable signals (46, 58, 60, 80). This receiver (18) performs its signal quality statistic monitoring while a data stream (36) is being extracted from a received communication signal.
(FR)L'invention concerne un système de communications (10), comprenant un émetteur (20) qui émet des signaux programmables (46, 58, 60, 80) pouvant être utilisés pour compenser des déséquilibres de signaux de phase en quadrature dus audit l'émetteur. Un récepteur (18) du système (10) est placé à distance de l'émetteur (20) et génère une statistique de qualité (102, 112) de signal surveillée dans une boucle de rétroaction à réaction lente, de façon à formuler des ordres qui indiquent comment programmer les signaux programmables (46, 58, 60, 80). Ce récepteur (18) exécute la statistique de qualité de signal pendant qu'un train de données (36) est extrait du signal de communication reçu.
