LOCALIZATION OF WIRELESS NODES

A method for localizing a wireless node includes synchronizing a respective time reference of a plurality of wideband spectrum-sensing units (20a, 20b, 20c, 20d, generally 20) and a master transceiver (14). A sensing location of each wideband spectrum-sensing unit (20) is stored in a first memory. E...

Zusammenfassung:	A method for localizing a wireless node includes synchronizing a respective time reference of a plurality of wideband spectrum-sensing units (20a, 20b, 20c, 20d, generally 20) and a master transceiver (14). A sensing location of each wideband spectrum-sensing unit (20) is stored in a first memory. Each wideband spectrum-sensing unit stores in a second memory a plurality of time-limited samples of a transmission received from a slave transceiver (16). The time limit of the transmission is determined by the master transceiver (14), receiving the transmission. The samples from the second memory are correlated with a corresponding plurality of reconstructed samples stored in the first memory to form a respective power delay profile for each of the of the wideband spectrum-sensing units (20). A slave location of the slave transceiver is determined by applying a Time Difference Of Arrival method to the respective power delay profiles.
