Provided is an apparatus and method for analyzing identification (ID) signals by converting radio frequency (RF) signals which are transmitted with an ID signal added thereto by a transmitting part, e.g., a plurality of transmitters or repeaters, into signals of a desired band; creating ID signals that are identical to the ID signals added to the RF signals; calculating correlation values between the converted signals and the created ID signals based on partial correlation; and extracting channel profile of multi-path signals caused by a channel between the transmitting part and the ID signal analyzing apparatus from the correlation value. The technology of the present research is applied to broadcasting and communication.

L'invention concerne un appareil et un procédé d'analyse de signaux d'identification (ID) par conversion de signaux radiofréquence (RF) émis avec un signal ID ajouté à ceux-ci au moyen d'une unité d'émission, et notamment une pluralité d'émetteurs ou de répéteurs, en signaux d'une bande souhaitée, par création de signaux ID identiques aux signaux ID ajoutés aux signaux RF, par calcul de valeurs de corrélation entre les signaux convertis et les signaux ID créés sur la base d'une corrélation partielle, et par extraction d'un profil de canal de signaux multivoies produits dans un canal entre l'unité d'émission et l'appareil d'analyse de signaux ID à partir de la valeur de corrélation. La technologie de la présente invention s'applique à la radiodiffusion et à la communication.
