Abstract

L'invention concerne un système de communications (réseau), tel qu'un système de communications à ondes millimétriques (MMW), comprenant une série de chaînes de noeuds constituées d'un noeud intermédiaire (#1), d'un premier noeud adjacent (#2) situé sur un côté du noeud intermédiaire, et d'un second noeud adjacent (#3) situé sur le côté opposé dudit noeud intermédiaire, chacun de ces noeuds étant doté d'un émetteur, d'un récepteur, d'une première antenne placée au niveau du noeud intermédiaire (#1) destinée à émettre et à recevoir via une première liaison aboutissant au second noeud adjacent (#3), et d'une seconde antenne placée au niveau du noeud intermédiaire (#1) destinée à émettre et à recevoir via une seconde liaison aboutissant au premier noeud adjacent (#2); et des moyens permettant de supprimer des interférences dans l'émetteur ou le récepteur du noeud intermédiaire ou dans les deux à la fois. Différents modes de réalisation d'égaliseur multidimensionnel permettent de supprimer des interférences. Un dispositif de suppression d'interférences d'émission comprend des moyens permettant de convolutionner un signal destiné à l'émission vers un noeud adjacent à l'aide d'une forme égalisée d'un signal destiné à l'émission vers un autre noeud adjacent. Un dispositif de suppression d'interférences de réception peut être réalisé avec ou sans atténuation de bruit de phase. Un dispositif de suppression d'interférences d'émission peut être réalisé avec ou sans atténuation de bruit de phase. Ladite invention peut être mise en oeuvre avec ou sans commande automatique de la puissance de l'émetteur (ATPC) au niveau des noeuds. Elle peut également mettre en oeuvre différentes modulations via des liaisons entre les différents noeuds du réseau. L'invention concerne également des techniques permettant d'établir des liaisons sur ledit réseau.
