Title (EN) THE METHOD FOR OBTAINING SNR OF BURST SIGNAL GSM SYSTEM
(FR) PROCEDE POUR OBTENIR LE SNR D'UN SIGNAL EN RAFALE DANS UN SYSTEME GSM
Abstract: front page image
(EN)The present invention relates to a method for obtaining SNR of burst signal in GSM system. This method separates the energy of desired signal and the energy of noise from the total energy of the burst signal by utilizing the relationship of the burst signal that is received by the receiver of base station and the known training sequence, in order to obtain the SNR (the ratio of signal and noise) of the burst signal. This method is effective, simple and practical, and is easy to be practiced systematically.
(FR)L'invention concerne un procédé permettant d'obtenir le SNR d'un signal en rafale dans un système GSM. Le procédé sépare l'énergie d'un signal voulu et l'énergie du bruit de l'énergie totale du signal en rafale en utilisant la relation dudit signal reçu par le récepteur de la station de base et la séquence de formation connue, afin d'obtenir le rapport signal-bruit (SNR) du signal en rafale. Ce procédé efficace, simple et pratique, est facile à mettre en oeuvre de façon systématique.
