Joint RADAR communication (JRC) systems that use orthogonal frequency division multiplexing (OFDM) can be compromised by an adversary that re-produces the received OFDM signal crea…
Range-Doppler Spoofing in OFDM Signals for Preventing Wireless Passive Emitter Tracking
Antonios Argyriou
Passive emitter tracking (PET) algorithms can estimate both the range and Doppler of a wireless emitter when it uses orthogonal frequency division multiplexing (OFDM). In this pape…
Obfuscation of Human Micro-Doppler Signatures in Passive Wireless RADAR
Antonios Argyriou
When wireless communication signals impinge on a moving human they are affected by micro-Doppler. A passive receiver of the resulting signals can calculate the spectrogram that pro…
Doppler Spoofing in OFDM Wireless Communication Systems
Antonios Argyriou, Dimitrios Kosmanos
In this paper we present a method that prevents an unauthorized receiver (URx) from correctly estimating the Doppler shift present in an orthogonal frequency division multiplexing…
Long Short Term Memory Networks for Bandwidth Forecasting in Mobile Broadband Networks under Mobility
