Dans les récepteurs à multiplexage par répartition orthogonale de la fréquence (OFDM) à conversion directe, l'impact de l'inadéquation I/Q dépendant de la fréquence (IQ-M) avec le décalage de fréquence porteuse (CFO) doit être pris en compte. Une estimation assistée par préambule est développée pour contourner l'IQ-M dépendant de la fréquence avec CFO. Les résultats d'une simulation et d'une expérience montrent que la méthode proposée pourrait fournir une bonne efficacité d'estimation et améliorer les performances du système. De plus, le système proposé est compatible avec les normes actuelles des réseaux locaux sans fil.

Abstract: In direct-conversion orthogonal frequency division multiplexing (OFDM) receivers, the impact of frequency-dependent I/Q mismatch (IQ-M) with carrier frequency offset (CFO) must be considered. A preamble-assisted estimation is developed to circumvent the frequency-dependent IQ-M with CFO. The results of a simulation and an experiment show that the proposed method could provide good estimation efficiency and enhance the system performance. Moreover, the proposed scheme is compatible with current wireless local area network standards.
