Abstract

Système et procédé de réduction des interférences entre canaux adjacents, spécialement dans les systèmes de radiotéléphonie de type AMCD. Des transmissions en diversité sont prévues pour transmettre les signaux les plus faibles en couplant les versions retardées ou avancées desdits signaux (2) à une antenne (6) en train d'émettre sur une fréquence (1) adjacente.
