Enhancing Privacy in Radar-Based Vital Sign Monitoring Via Non-Linear FMCW Waveforms

ICASSP 2025accepted

Vital sign monitoring via a phased array radar transmitting continuous-wave (CW) or linear frequency-modulated continuous-wave (FMCW) offers contactless, low-cost, continuous monitoring of vital signs, i.e., human heart rate and breathing rate. In this paper, we demonstrate that, besides the authori…

How Secure is the Time-Modulated Array-Enabled OFDM Directional Modulation?

ICASSP 2024accepted

Time-modulated arrays (TMA) transmitting orthogonal frequency division multiplexing (OFDM) waveforms achieve physical layer security by allowing the signal to reach the legitimate destination undistorted, while making the signal appear scrambled in all other directions. In this paper, we examine how…
