Velocity profiler in IEEE 802.22 based PCL system

In this paper we focus on a White-Space Passive Coherent Location (WS-PCL) system that exploits signals emitted by IEEE 802.22 devices. To cope with the very low transmitted EIRP of these emitters, the analysed system exploits all the useful signals in each frame, i.e. those coming from the Base Station (BS) in the down-stream subframe and those from the scheduled Customer Premise Equipments (CPEs) in the upstream sub-frame. We derive a multistatic velocity profiling algorithm for the estimation of target velocity vector whose performance is compared with that of a system that exploits only the signal emitted by the BS.
