Abstract
(EN)
A signal received by antennas (1, 2) is adaptive array processed by a DSP to produce an array output. A reception timing control section (30) shifts the timing of received signal sampling by A/D converters (3, 4) while monitoring the MSE of the array output and a reference signal and determines an optimal sampling point (reception position) where the sampling error is minimum.
(FR)
Selon l'invention, un signal reçu par des antennes (1, 2) est traité selon une technique de réseau adaptatif par un DSP en vue de produire une sortie de réseau. Une section de commande de la synchronisation de la réception (30) transfère la synchronisation de l'échantillonnage du signal reçu par des convertisseurs A/N (3, 4) tout en surveillant le MSE de la sortie de réseau et un signal de référence, et détermine également un point d'échantillonnage optimal(position de réception) au niveau duquel l'erreur d'échantillonnage est minimum.
