SensWear: An Open, Modular, and AI-Ready Wearable Platform
Dariush Salami, Behzad Salami, Huseyin Yigitler
Wearable AI/ML research needs raw, synchronized, and reconfigurable multimodal data, but consumer devices are closed and many research platforms remain tied to one embodiment or se…
Adaptive Internal Calibration for Temperature-Robust mmWave FMCW Radars
Dariush Salami, Nima Bahmani, Hüseyin Yiğitler +1
We present a novel internal calibration framework for Millimeter- Wave (mmWave) Frequency-Modulated Continuous-Wave (FMCW) radars to ensure robust performance under internal temper…
Covert backscatter communication with directional MIMO
Roberto Di Candia, Saneea Malik, Huseyin Yiğitler +1
We study a backscatter communication protocol over a AWGN channel, where a transmitter illuminates a tag with a directional multi-antenna. The tag performs load modulation on the s…
Optimum Multi-Antenna Ambient Backscatter Receiver for General Binary-Modulated Signal
Xiyu Wang, Hüseyin Yiğitler, Riku Jäntti
Ambient backscatter communication (AmBC) is becoming increasingly popular for enabling green communication amidst the continual development of the Internet-of-things paradigm. Effo…
Coherent Multi-antenna Receiver for BPSK-modulated Ambient Backscatter Tags
Xiyu Wang, Hüseyin Yiğitler, Ruifeng Duan +2
Ambient Backscatter Communication (AmBC) is an emerging communication technology that can enable green Internet-of-Things deployments. The widespread acceptance of this paradigm is…
Two-way covert quantum communication in the microwave regime
R. Di Candia, H. Yiğitler, G. S. Paraoanu +1
Quantum communication addresses the problem of exchanging information across macroscopic distances by employing encryption techniques based on quantum mechanical laws. Here, we adv…
RSS Models for Respiration Rate Monitoring
Hüseyin Yiğitler, Ossi Kaltiokallio, Roland Hostettler +3
Received signal strength based respiration rate monitoring is emerging as an alternative non-contact technology. These systems make use of the radio measurements of short-range com…
On the Achievable Rate of Bi-Static Modulated Re-Scatter Systems
Ruifeng Duan, Riku Jäntti, Hüseyin Yiğitler +1
In ambient re-scatter communications, devices convey information by modulating and re-scattering the radio frequency signals impinging on their antennas. In this correspondence, we…
Detector Based Radio Tomographic Imaging
Hüseyin Yiğitler, Riku Jäntti, Ossi Kaltiokallio +1
Received signal strength based radio tomographic imaging is a popular device-free indoor localization method which reconstructs the spatial loss field of the environment using meas…
Enhancing the Accuracy of Device-free Localization Using Spectral Properties of the RSS
Ossi Kaltiokallio, Hüseyin Yiğitler, Riku Jäntti
Received signal strength based device-free localization has attracted considerable attention in the research society over the past years to locate and track people who are not carr…
Detecting Human-induced Reflections using RSS of Narrowband Wireless Transceivers
Hüseyin Yiğitler, Riku Jäntti, Ossi Kaltiokallio
Radio frequency sensor networks are becoming increasingly popular as an indoor localization and monitoring technology for gaining unobtrusive situational awareness of the surroundi…
A Three-State Received Signal Strength Model for Device-free Localization
Ossi Kaltiokallio, Hüseyin Yiğitler, Riku Jäntti
The indoor radio propagation channel is typically modeled as a two-state time-variant process where one of the states represents the channel when the environment is static, whereas…
Catch a Breath: Non-invasive Respiration Rate Monitoring via Wireless Communication
Ossi Kaltiokallio, Hüseyin Yigitler, Riku Jäntti +1
Radio signals are sensitive to changes in the environment, which for example is reflected on the received signal strength (RSS) measurements of low-cost wireless devices. This info…
