| Zusammenfassung: | The invention relates to a securing method for auxiliary data streams dropped and inserted in any station (52) along a digital radio relay route, in which the redundancy in the main signal is calculated in every intermediate station in order to obtain, hop by hop, quality information which is retransmitted in the radio data frame in order to recover at every point of the radio link the quality information for upstream hops. The application is particularly in the field of directional radio links.
L'invention concerne un procédé de sécurisation de trains auxiliaires insérés-extraits dans une station quelconque (52) le long d'une artère hertzienne numérique, dans lequel on effectue un calcul de redondance sur le signal principal, dans chacune des stations intermédiaires, afin d'élaborer des informations de qualité bond par bond que l'on retransmet dans la trame hertzienne afin de récupérer en tout point de la liaison hertzienne les informations de qualité de tous les bonds en amont. Application notamment au domaine des faisceaux hertziens. |
