Title (EN) APPARATUS AND METHOD FOR RF INTERFERENCE AVOIDANCE IN AN AUTOMOTIVE DETECTION SYSTEM
(FR) APPAREIL ET PROCÉDÉ POUR ÉVITER L’INTERFÉRENCE RF DANS UN SYSTÈME DÉTECTION POUR AUTOMOBILE
Abstract:
(EN) A method of mitigates RF interference from an RF interferer. An RF signal is received at an RF transceiver during a time period. The RF signal that includes, for at least a portion of the time period, an interference signal having a cyclic transmission pattern with at least one deterministic feature. The received RF signal is analyzed in order to determine timing information for the at least one deterministic feature and the associated interference signal cyclic transmission pattern. Transmission of the RF signals from the RF transceiver are synchronized with the interference signal transmission pattern based on the determined timing information to mitigate interference between the RF signals and the interference signal.
(FR) La présente invention concerne un procédé d’atténuation d’interférence RF provenant d’un brouilleur RF. Un signal RF est reçu au niveau d’un émetteur-récepteur RF pendant une période de temps. Le signal RF qui comprend, pendant au moins une partie de la période de temps, un signal d’interférence ayant un motif d’émission cyclique avec au moins une caractéristique déterministe. Le signal RF reçu est analysé afin de déterminer des informations de temporisation pour l’au moins une caractéristique déterministe et le motif d’émission cyclique de signal d’interférence associé. L’émission des signaux RF provenant de l’émetteur-récepteur RF est synchronisée avec le motif d’émission de signal d’interférence sur la base des informations de temporisation déterminées pour atténuer l’interférence entre les signaux RF et le signal d’interférence.
