Un nouveau schéma de synchronisation temporelle est proposé pour une utilisation dans la communication inter-véhicules (IVC) avec un système de transport intelligent distribué (ITS) autonome. Le système détermine le timing de transmission du signal par paquets dans le réseau IVC et utilise le timing de l'intervalle de garde (GI) dans le signal de multiplexage par répartition orthogonale de la fréquence (OFDM) actuellement utilisé pour les diffusions terrestres dans le système de télévision numérique japonais (ISDB-T). Ce signal est utilisé car on s'attend à ce que le marché automobile exige dans un avenir proche que les voitures soient capables de recevoir des émissions de télévision numérique terrestre. L'utilisation des émissions par les automobiles présuppose que les récepteurs embarqués soient capables de détecter avec précision les données de synchronisation GI dans un rapport porteuse sur bruit (CNR) extrêmement faible, indépendamment d'un environnement multitrajets sévère qui introduira une large dispersion dans l'arrivée du signal. fois. Par conséquent, nous avons analysé les signaux de diffusion réels reçus dans un véhicule en mouvement lors d'une expérience sur le terrain et avons montré que le signal de synchronisation GI est détecté avec la précision souhaitée, même dans le cas d'environnements à CNR extrêmement faible. Certaines réflexions ont également été formulées sur la manière d'utiliser ces résultats.

Abstract: A novel timing synchronizing scheme is proposed for use in inter-vehicle communication (IVC) with an autonomous distributed intelligent transport system (ITS). The scheme determines the timing of packet signal transmission in the IVC network and employs the guard interval (GI) timing in the orthogonal frequency divisional multiplexing (OFDM) signal currently used for terrestrial broadcasts in the Japanese digital television system (ISDB-T). This signal is used because it is expected that the automotive market will demand the capability for cars to receive terrestrial digital TV broadcasts in the near future. The use of broadcasts by automobiles presupposes that the on-board receivers are capable of accurately detecting the GI timing data in an extremely low carrier-to-noise ratio (CNR) condition regardless of a severe multipath environment which will introduce broad scatter in signal arrival times. Therefore, we analyzed actual broadcast signals received in a moving vehicle in a field experiment and showed that the GI timing signal is detected with the desired accuracy even in the case of extremely low-CNR environments. Some considerations were also given about how to use these findings.
