In a communications system wherein a broadcast signal is received by a plurality of antennas each connected to a receiver, the resulting plurality of received signals are jointly subjected to automatic frequency correction (AFC) before interference rejection combining (IRC) or maximal ratio combining (MRC) processing to output an estimate of the broadcast signal. The joint automatic frequency correction processing involves computing and applying a frequency offset on a sample by sample basis to each of the received signals to output corresponding frequency corrected received signals for IRC or MRC processing.
Dans un système de communications dans lequel un signal de radiodiffusion est reçu par plusieurs antennes connectées, chacune, à un récepteur, la pluralité résultante de signaux reçus est soumise, conjointement, à une correction automatique de fréquence (AFC) avant le traitement de combinaison de rejet de bruits (IRC) ou le traitement de combinaison à rapport maximal (MRC) aux fins de la production d'une valeur estimative du signal de radiodiffusion. Le traitement conjoint de correction automatique de fréquence repose sur le calcul d'un décalage de fréquence et son application, selon un processus échantillon par échantillon, à chaque signal reçu afin de produire des signaux reçus correspondants à fréquence corrigée pour traitement IRC ou MRC.
