Dans cet article, une méthode d'interpolation de sous-espace de signal pour construire une base de données continue d'empreintes digitales pour la localisation radio est proposée. Lors de l'utilisation de la technique des empreintes digitales, l'amélioration de la précision de l'estimation de localisation nécessite une résolution spatiale très fine de la base de données, ce qui nécessite beaucoup de temps pour collecter les données nécessaires à la constitution de la base de données. Un sous-espace de signal interpolé est présenté pour obtenir une résolution spatiale fine de la base de données d'empreintes digitales. L'angle d'arrivée (AOA) et le sous-espace de signal mesuré à des emplacements connus sont nécessaires pour obtenir les sous-espaces de signal interpolés. L'efficacité de cette méthode est vérifiée par une expérience en extérieur et l'emplacement estimé à l'aide de cette méthode a été comparé à ceux utilisant l'empreinte géométrique calculée et les techniques d'empreinte digitale du sous-espace de signal mesuré.

Abstract: In this paper, a method of the signal subspace interpolation to constructing a continuous fingerprint database for radio localization is proposed. When using the fingerprint technique, enhancing the accuracy of location estimation requires very fine spatial resolution of the database, which entails much time in collecting the data to build up the database. Interpolated signal subspace is presented to achieve a fine spatial resolution of the fingerprint database. The angle of arrival (AOA) and the measured signal subspace at known locations are needed to obtain the interpolated signal subspaces. The effectiveness of this method is verified by an outdoor experiment and the estimated location using this method was compared with those using the geometrically calculated fingerprint and the measured signal subspace fingerprint techniques.

AB - In this paper, a method of the signal subspace interpolation to constructing a continuous fingerprint database for radio localization is proposed. When using the fingerprint technique, enhancing the accuracy of location estimation requires very fine spatial resolution of the database, which entails much time in collecting the data to build up the database. Interpolated signal subspace is presented to achieve a fine spatial resolution of the fingerprint database. The angle of arrival (AOA) and the measured signal subspace at known locations are needed to obtain the interpolated signal subspaces. The effectiveness of this method is verified by an outdoor experiment and the estimated location using this method was compared with those using the geometrically calculated fingerprint and the measured signal subspace fingerprint techniques.
