In a TDD wireless communication system between transmitters and associated receivers, automatic gain control of a receiver is only applied during the corresponding time slot within the TDD signal time frame architecture. Successive received signal strengths are measured and gain levels are stored as estimates for an initial gain level in future time slots of the TDD signal. Estimating techniques, such as averaging or trending of received signal strength over successive time slots, and averaging or trending of gain level settings, provide improved estimation of future initial gain levels.
Dans un système de communication sans fil duplex à répartition dans le temps (TDD) entre émetteurs et récepteurs associés, une commande automatique de gain de récepteur n'est appliquée que durant le créneau temporel dans l'architecture de trame temporelle du signal TDD. On mesure des intensité de signaux successivement reçus et les niveaux de gain sont mémorisés en tant que valeurs estimatives pour un niveau de gain initial d'autres créneaux temporels du signal TDD. Des techniques d'estimation, telles que des techniques de moyennage ou de recherche de tendance d'intensité du signal reçu au cours de créneaux temporels successifs ainsi que de moyennage ou de recherche de tendance d'établissements de niveau de gain, fournissent des valeurs estimatives améliorées concernant de futurs niveaux de gain initial.
