The present invention relates to a method of compiling transmitter-to-receiver relationships in a radio system. The radio system includes at least two receivers (B48, B42) and at least one transmitter (MS1) located in at least one radio coverage area (C42) of the receivers (B42). The method for a single transmitter (MS1) comprises the steps of: sending a signal (ARM) having known power (Put) on a transmission channel allocated to said transmitter (MS1); measuring in at least one of the receivers (B48, B42) the power received (S48, S42) from the transmitted signal (2, ACCESS), it being guaranteed that the signal will be a solitary signal upon reception; calculating the amplification (g~48, g~42) of the signal (ARM) received in the receiver; and storing the calculated amplification (g~48, g~42) in a storage location in the radio system.
La présente invention se rapporte à un procédé servant à établir des rapports émetteur-récepteur dans un système radio. Le système radio comprend au moins deux récepteurs (B48, B42) et au moins un émetteur (MS1), situés dans au moins une zone (C42) de desserte des récepteurs (B42). Le procédé destiné à un récepteur unique (MS1) consiste en ce qui suit: envoyer un signal (ARM) ayant une puissance connue (Put) sur une voie de transmission attribuée audit émetteur (MS1); pour au moins un des récepteurs (B48, B42), mesurer la puissance (S48, S42) qui a été reçue du signal transmis (2, ACCESS), ce qui garantit qu'à la réception le signal se présente comme un signal isolé; calculer l'amplification (g^48, g^42) du signal (ARM) reçu par le récepteur; et stocker l'amplification calculée (g^48, g^42) dans un emplacement de stockage du système radio.
