Cet article étudie expérimentalement l'effet de la compensation d'erreur de fréquence fournie par le contrôle automatique de fréquence de démodulation (AFC) utilisant le canal de synchronisation (SCH) dans l'accès radio OFDM en liaison descendante. Le récepteur OFDM mis en œuvre compense l'erreur de fréquence provoquée par la différence de fréquence entre une station de base (BS) et un équipement utilisateur (UE) à l'aide d'un signal SCH multiplexé par répartition dans le temps et celle provoquée par le décalage Doppler généré par la mobilité d'un utilisateur utilisant des signaux de référence avec multiplexage échelonné. Les résultats expérimentaux montrent que même lorsque la fréquence d'oscillateur standard de l'UE ne peut pas être amenée à suivre la fréquence la plus précise d'une BS, la démodulation AFC peut supprimer l'erreur de fréquence résiduelle à un niveau suffisamment faible, c'est-à-dire à moins de 0.3 ppm, en utilisant le SCH ainsi que la dégradation du taux d'erreur de bloc des signaux de commande du canal physique de diffusion est légère, c'est-à-dire à environ 0.1 dB près, par rapport au cas sans erreur de fréquence pour des vitesses supérieures à 350 km/h.

Abstract: This paper experimentally investigates the effect of frequency error compensation provided by demodulation automatic frequency control (AFC) using the Synchronization Channel (SCH) in downlink OFDM radio access. The implemented OFDM receiver compensates for the frequency error caused by the difference in frequency between a base station (BS) and a user equipment (UE) using a time-division multiplexed SCH signal and that caused by the Doppler shift generated by the mobility of a user using reference signals with staggered multiplexing. Experimental results show that even when the standard oscillator frequency of the UE cannot be made to track the more accurate frequency of a BS, demodulation AFC can suppress the residual frequency error to a sufficiently low level, i.e., within 0.3 ppm, using the SCH so that the degradation in the block error rate of the physical broadcast channel control signals is slight, i.e., within approximately 0.1 dB, with respect to the case without frequency error for speeds greater than 350 km/h.
