Multi-channel self-interference cancellation is provided in relayed electromagnetic communication (Fig. 4) between a first device and one or more other devices on one or more shared frequency channels. Specifically, near signals are generated at the first device and transmitted to a relay station. A composite signal is received at the first device from the relay station containing relayed versions of the near signals and relayed versions of remote signals transmitted from the one or more other devices, the composite signal having frequency channels including the one or more shared frequency channels, each shared frequency channel occupied by at least one of the relayed near signals and one of the relayed remote signals. One or more cancellation signals are selectively generated, each having a frequency band corresponding to one of the shared frequency channels. The cancellation signals are combined with the composite signal to produce a desired signal representing the relayed remote signals.

L'invention concerne un procédé permettant de supprimer l'autobrouillage multicanal dans une communication électromagnétique relayée (figure), établie entre un premier dispositif et un ou plusieurs autres dispositifs sur un ou plusieurs canaux de fréquences communs. Précisément, des signaux proches sont générés au niveau du premier dispositif, et transmis à une station relais. Un signal composite émis par la station relais est reçu au niveau du premier dispositif, ledit signal contenant des versions relayées des signaux proches et des versions relayées de signaux distants émis par le ou les autres dispositifs, le signal composite possédant des canaux de fréquences contenant le ou les canaux de fréquences communs, chaque canal de fréquences commun étant occupé par au moins l'un des signaux proches relayés et l'un des signaux distants relayés. Un ou plusieurs signaux de suppression sont générés sélectivement, chacun possédant une bande de fréquence correspondant à l'un des canaux de fréquences communs. Les signaux de suppression sont combinés avec le signal composite pour produire un signal souhaité représentant les signaux distants relayés.
