Title (EN) CORRELATION SYSTEMS AND METHODS WITH ERROR COMPENSATION
(FR) SYSTÈMES ET PROCÉDÉS DE CORRÉLATION À COMPENSATION D'ERREUR
Abstract: front page image
(EN)A correlation system, such as a correlation optical time domain reflectometer (OTDR) system, transmits a correlation sequence, such as an M-sequence, and measures the returns of the correlation sequence over time. The system correlates the transmitted sequence with the returns to provide correlation measurement values that respectively correspond to different distances from the point of transmission. A correlation error compensation element adjusts each correlation measurement value in order to cancel the contribution of the correlation error floor from the measurements to provide compensated measurement values that are substantially free of the effects of the correlation error floor.
(FR)L'invention porte sur un système de corrélation, tel qu'un système de réflectométrie optique temporelle (OTDR) à corrélation, lequel système émet une séquence de corrélation, telle qu'une séquence M, et mesure les retours de la séquence de corrélation au cours du temps. Le système corrèle la séquence émise aux retours de façon à fournir des valeurs de mesure de corrélation qui correspondent respectivement à différentes distances à partir du point d'émission. Un élément de compensation d'erreur de corrélation ajuste chaque valeur de mesure de corrélation afin d'éliminer la contribution du plancher d'erreur de corrélation aux mesures de façon à produire des valeurs de mesure compensées qui sont sensiblement exemptes des effets du plancher d'erreur de corrélation.
