White space Passive Coherent Location system based on IEEE 802.22 [PDF]
, 2015 In this work we describe a Passive Coherent Location (PCL) system that exploits the signals emitted by IEEE 802.22 devices, operating in the white spaces of the VHF/UHF TV bands. The analysed system is called White Space PCL (WS-PCL).
