Methods are provided for locating a mobile radio communication device with a receiver detecting electromagnetic identification signals broadcast by transmitters in a confined environment, or an object with a transmitter periodically broadcasting an electromagnetic identification signal detectable by a plurality of receivers of a localization infrastructure. The receiver of the mobile radiocommunication device, or the plurality of receivers of the localization infrastructure, determine identification data indicative of strength of received identification signals, forming an identification data matrix which is processed to obtain an identification data matrix with reduced noise, from which a characteristic identification vector is extracted including a characteristic identification data element for each transmitter or receiver. Position coordinates of the mobile radio communication device or of the object are determined by minimizing an error in calculating distances between position of the mobile radio communication device, or of the object, and position of at least three transmitters, respectively receivers.

Abstract
Methods are provided for locating a mobile radio communication device with a receiver detecting electromagnetic identification signals broadcast by transmitters in a confined environment, or an object with a transmitter periodically broadcasting an electromagnetic identification signal detectable by a plurality of receivers of a localization infrastructure. The receiver of the mobile radiocommunication device, or the plurality of receivers of the localization infrastructure, determine identification data indicative of strength of received identification signals, forming an identification data matrix which is processed to obtain an identification data matrix with reduced noise, from which a characteristic identification vector is extracted including a characteristic identification data element for each transmitter or receiver. Position coordinates of the mobile radio communication device or of the object are determined by minimizing an error in calculating distances between position of the mobile radio communication device, or of the object, and position of at least three transmitters, respectively receivers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
