概要
- 論文の詳細を見る
In this paper, a new approach in generating a fingerprinting database for the subspace matching localization technique is proposed. When using the fingerprinting technique, enhancing the accuracy of location estimation requires very fine spatial resolution of the database, which entails more time and power in building up the database. Interpolated signal subspaces obtained from measured signal subspaces are proposed to obtain a fine spatial resolution of the signal subspace data which are used as the fingerprint. The accuracy of this method is verified by an outdoor experiment in which the mobile terminal can be detected accurately when the spatial sampling interval is 20m for the measurement to get the signal subspace.
