Cet article propose une nouvelle technique d'étalonnage de réseau d'antennes qui utilise la sélection de fréquence dans les systèmes à accès multiple par répartition orthogonale de la fréquence (OFDMA)/duplexage par répartition dans le temps (TDD). Dans le procédé proposé, des sous-bandes ou fréquences présentant de bonnes conditions de canal sont initialement sélectionnées pour les mesures de canal. L'étalonnage relatif est effectué au niveau des sous-bandes sélectionnées, ce qui compense l'inadéquation des gains analogiques dans plusieurs antennes à l'aide des paramètres de canal de liaison montante et descendante mesurés. De plus, les paramètres d'étalonnage sont interpolés dans le domaine fréquentiel pour toute la bande passante. L'étalonnage proposé maintient une réciprocité de canal précise pour toute la bande passante par rapport à l'étalonnage conventionnel qui n'utilise pas la sélection de fréquence. La technique d'étalonnage proposée est efficace pour exploiter la réciprocité des canaux au niveau de la station de base et des terminaux avec une quantité de rétroaction réalisable et un fonctionnement à faible coût.

Abstract: This paper proposes a new antenna array calibration technique which uses frequency selection in orthogonal frequency division multiple access (OFDMA)/time division duplexing (TDD) systems. In the proposed method, subbands or frequencies of good channel conditions are initially selected for channel measurements. The relative calibration is performed at the selected subbands, which compensates for mismatch of analogue gains in multiple antennas using the measured uplink and downlink channel parameters. Furthermore, the calibration parameters are interpolated in the frequency domain for the whole bandwidth. The proposed calibration maintains accurate channel reciprocity for the whole bandwidth compared to the conventional calibration which does not use the frequency selection. The proposed calibration technique is effective in exploiting channel reciprocity at both base station and terminals with feasible amount of feedback and low-cost operation.
