Abstract

Ce système comporte une pluralité de stations de réception reliées par une ligne commune ou poste central. Plusieurs stations sont susceptibles de capter les émissions du poste mobile et c'est seule la station de réception qui capte le mieux cette émission qui effectue la transmission de l'émission du poste mobile vers le poste central. Application : communications radioélectriques pour chemin de fer.
