DESCRIPTION:Wireless research is increasingly moving toward Integrated Sens
 ing and Communication (ISAC)\, which unifies radar and communication on a 
 shared platform to improve spectral efficiency and reduce hardware costs. 
 In this talk\, we present a covert communication framework for Frequency-M
 odulated Continuous Wave (FMCW) radar systems that embeds binary symbols d
 irectly into the radar chirp. By selectively activating or suppressing tra
 nsmissions at predefined time–frequency locations\, information is encod
 ed without disrupting core radar functionality. A synchronized receiver de
 codes the embedded bits based on energy detection\, enabling low-overhead 
 control signaling without requiring additional spectrum. The proposed sche
 me is compatible with existing FMCW hardware and introduces a stealthy com
 munication layer with minimal impact on range estimation and resolution. A
 nalytical and simulation results demonstrate reliable bit recovery\, and a
  USRP-based software-defined radar prototype validates feasibility under p
 ractical SNR conditions. This work highlights covert embedding as a lightw
 eight pathway toward practical ISAC systems for automotive\, defense\, and
  IoT applications.\n\nSpeaker(s): \, Shiwen\n\nAv. Eugenio Garza Sada 2501

X-ALT-DESC:Description: <br /><p>Wireless research is increasingly moving t
 oward Integrated Sensing and Communication (ISAC)\, which unifies radar an
 d communication on a shared platform to improve spectral efficiency and re
 duce hardware costs. In this talk\, we present a covert communication fram
 ework for Frequency-Modulated Continuous Wave (FMCW) radar systems that em
 beds binary symbols directly into the radar chirp. By selectively activati
 ng or suppressing transmissions at predefined time&ndash\;frequency locati
 ons\, information is encoded without disrupting core radar functionality. 
 A synchronized receiver decodes the embedded bits based on energy detectio
 n\, enabling low-overhead control signaling without requiring additional s
 pectrum. The proposed scheme is compatible with existing FMCW hardware and
  introduces a stealthy communication layer with minimal impact on range es
 timation and resolution. Analytical and simulation results demonstrate rel
 iable bit recovery\, and a USRP-based software-defined radar prototype val
 idates feasibility under practical SNR conditions. This work highlights co
 vert embedding as a lightweight pathway toward practical ISAC systems for 
 automotive\, defense\, and IoT applications.</p>
