In a multi-channel receiver system (100) embodying the invention, a "trained" receiver channel which is active and propagating data signals may be used to train any other receiver channel. Each receiver channel of the system has an input (105) and an output (123), with each input for receiving a different portion of an original data signal. Each receiver channel includes adaptive filter device (10) coupled between its input and its output for propagating the signals received at its input to its output. In accordance with the invention, a first trained receiver channel is used to train a second receiver channel by coupling the output of the first receiver channel to the output of the second receiver channel for training the adaptive filter device of the second receiver channel. The training of the second receiver is completed by transmitting the same data to the first and second receiver channels.

Dans un système récepteur multicanal (100) matérialisant l'invention, un canal "formé", lequel est actif et propage des signaux de données, peut être utilisé pour assurer l'apprentissage de n'importe quel autre canal du récepteur. Chaque canal du système comporte une entrée (105) et une sortie (123), chaque entrée recevant une partie différente d'un signal de données initial. Chaque canal comprend un filtre adaptatif (10) couplé entre son entrée et sa sortie en vue de propager jusqu'à cette dernière les signaux reçus au niveau de son entrée. Un premier canal "formé" sert à assurer l'apprentissage d'un deuxième canal par couplage de la sortie du premier canal à la sortie du deuxième canal en vue d'assurer l'apprentissage du filtre adaptatif du deuxième canal. L'apprentissage de ce dernier s'achève par la transmission des mêmes données aux premier et deuxième canaux du récepteur.
