Integrated Radar and Communication Via Linear-Motion Backscatter: A Proof of Concept

Integrated radar and communications systems conventionally rely on complex electronic radio-frequency modulation, presenting power and security limitations for low-power Internet of Things (IoT) nodes. This paper proposes a novel linear-motion backscatter communication framework that transforms controlled mechanical ki...

Comparative Study of Signal Processing and Machine Learning Algorithms for Contactless Respiratory Rate Estimation Using FMCW Radar

Respiratory rate (RR) is a vital physiological marker whose accurate and continuous monitoring holds particular clinical significance. Conventional contact-based sensors, while reliable, impose physical constraints that may cause discomfort and skin irritation. Radar-based sensing, particularly frequency-modulated cont...
