Abstract
A method for localizing a wireless node includes synchronizing a respective time reference of a plurality of wideband spectrum-sensing units and a master transceiver. A sensing location of each wideband spectrum-sensing unit 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. The time limit of the transmission is determined by the master transceiver, 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. A slave location of the slave transceiver is determined by applying a Time Difference Of Arrival method to the respective power delay profiles.
