METHOD FOR DETERMINING GEOMETRIC INFORMATION OF DEVICES IN MILLIMETER-WAVE NETWORKS
US10819453B2 | ES2725773B2
A method for determining geometric information of mmWave network devices is provided, comprising collecting measures, by at least one of the devices, of signal strength and SNR of a transmission received from another device of the mmWave network; the step of estimating angle information of the received signal to generate a set of informed particles (Pi) comprising the initial values of the state of each informed particle input in a modified particle filter; the modified particle filter causing the evolution of the set of informed particles (Pi) and of past particles (Pp) to obtain a set of evolved particles (Pe) which at the same time evolves to obtain a set of posterior particles (PPost) delivered by the modified particle filter. Finally, the modified particle filter delivers as output the final values of the geometric information of at least one device extracted from the delivered set of posterior particles (PPost).
Un método capaz de extraer la información necesaria de las señales de ondas milimétricas para poder estimar la localización del usuario de la red. No se necesitan incorporar sensores adicionales en el dispositivo y funciona en el interior de edificios. También ayuda a evitar y prevenir aquellos obstáculos situados entre un dispositivo de usuario y uno de los múltiples puntos de acceso a la red.
