Neste artigo, é proposto um método de interpolação de subespaço de sinal para a construção de um banco de dados contínuo de impressões digitais para localização de rádio. Ao usar a técnica de impressão digital, aumentar a precisão da estimativa de localização requer uma resolução espacial muito fina do banco de dados, o que implica muito tempo na coleta de dados para construir o banco de dados. O subespaço de sinal interpolado é apresentado para obter uma resolução espacial fina do banco de dados de impressões digitais. O ângulo de chegada (AOA) e o subespaço do sinal medido em locais conhecidos são necessários para obter os subespaços do sinal interpolado. A eficácia deste método é verificada por um experimento ao ar livre e a localização estimada usando este método foi comparada com aquelas que usam a impressão digital calculada geometricamente e as técnicas de impressão digital do subespaço de sinal medido.

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.
