Abstract

L'invention concerne un procédé pour régler automatiquement une unité d'accord à accès d'entrée unique et accès de sortie unique. L'invention concerne aussi un appareil pour communication radio utilisant ce procédé, par exemple un émetteur-récepteur radio. Un appareil pour communication radio selon l'invention comporte : une antenne (1) ; une unité d'accord à accès d'entrée unique et accès de sortie unique (4) ayant un accès d'entrée et un accès de sortie ; une liaison d'antenne (2) ; une unité de détection (3) ; une unité d'émission et de traitement du signal (8) qui applique une excitation à l'accès d'entrée, et qui délivre des "instructions de réglage d'unité d'accord", au moins une des instructions de réglage d'unité d'accord étant une "instruction de réglage d'unité d'accord initiale", au moins une des instructions de réglage d'unité d'accord étant une "instruction de réglage d'unité d'accord ultérieure" ; et une unité de contrôle (6) qui délivre un ou plusieurs "signaux de contrôle d'accord" à l'unité d'accord à accès d'entrée unique et accès de sortie unique.A method for automatically tuning a tuning unit with single input access and single output access. The invention also relates to an apparatus for radio communication using this method, for example a radio transceiver. An apparatus for radio communication according to the invention comprises: an antenna (1); a single-entry, single-exit port tuning unit (4) having one entry port and one exit port; an antenna link (2); a detection unit (3); a signal transmitting and processing unit (8) which applies an excitation to the input port, and which outputs "tuning unit setting instructions", at least one of the tuning set instructions tuning unit being an "initial tuning unit setting instruction", at least one of the tuning unit setting instructions being a "subsequent tuning unit setting instruction"; and a control unit (6) which outputs one or more "tuning control signals" to the single input port and single output port tuning unit.
