Abstract

Un método para mejorar los resultados de los sistemas de localización de radio que incorporan la optimización de los mínimos cuadrados ponderados, generaliza el método de los mínimos cuadrados ponderados usando unas métricas de probabilidad a posteriori (MAP) para incorporar las características del problema de posicionamiento específico (por ejemplo, el UTDOA). Los métodos de mínimos cuadrados ponderados típicamente se usan por sistemas de TDOA y sistemas de localización relacionados incluyendo el TDOAIAOA y los sistemas híbridos TDOAIGPS. Las características incorporadas incluyen información empírica acerca de los errores de TDOA y la distribución de probabilidad de la posición del móvil con respecto a otros elementos de red. Se proporciona una técnica para el modelado de la distribución de errores de TDOA y la posición del móvil a priori. Se proporciona un método para calcular una métrica de decisión MAP que usa los nuevos modelos de distribución de probabilidad. La comprobación con datos de campo muestra que este método obtiene una mejora significativa sobre los métodos de mínimos cuadrados ponderados (ver diagrama) existentes.
