A receiver in a frame based radio communication system includes a speech decoder of the source-filter type which is controlled by means including internal state variables updated on a frame by frame basis for modifying received filter defining parameters representing background sounds transmitted over a communication channel. The receiver includes means for detecting frame loss and means for concealing the effects of frame loss by restricting updating of at least one of the internal state variables.
Un récepteur dans un système de radiocommunication géré par trame comprend un décodeur vocal, du type filtre-source, commandé par un moyen (20, 22, 24) comprenant des variables d'état interne mis à jour selon un mode trame par trame afin de modifier des paramètres de définition de filtre reçus, représentant des bruits de fond transmis sur une voie de transmission. Le récepteur comprend des moyens (14) permettant de détecter la perte de trames, ainsi que des moyens (18) permettant de dissimuler les effets de perte de trame, par la restriction de la mise à jour d'au moins l'une des variables d'état interne.
