Abstract: front page image
(EN)The present invention relates to a system and method for terrestrial transmission of RF signals comprising: an antenna, where said antenna includes an active device and a passive device and a decoder. The passive device receives RF signals and passes the signals to the active device. The active device includes at least one amplifier, where active device down converts the RF signals to IF signals and applies a gain to at least one of the RF signals and the IF signals. The decoder connects to the antenna, where decoder receives and analyzes the IF signals from said antenna and upon receipt of the IF signals sends commands to the active device in order to maintain an acceptable IF signal, where said commands instruct the active device to selectively adjust the gain.
(FR)La présente invention concerne un système et un procédé de transmission terrestre de signaux RF, comprenant une antenne comprenant elle-même un dispositif actif, un dispositif passif et un décodeur. Le dispositif passif reçoit des signaux RF qu'il transmet au dispositif actif. Le dispositif actif, qui comprend au moins un amplificateur, convertit les signaux RF en signaux de fréquence intermédiaire (IF) et applique un gain à au moins un signal RF et aux signaux IF. Le décodeur, qui est connecté à l'antenne, analyse les signaux IF en provenance de cette dernière et, après réception desdits signaux, donne des instructions aux dispositif actif en vue du maintien d'un signal IF acceptable (par réglage sélectif du gain).
