Vision Guided Radar System for Enhanced Vital Signs Detection
Vital signs, such as heart and respiratory rate, provide critical insight into a person’s health. Radar has been used to remotely analyze and detect human activity and vital signs for many years. Despite all the great features such as motion sensitivity, privacy preservation, penetrability, and more, radar has limited spatial degrees of freedom...

Orthogonal Time Frequency Space (OTFS) Channel Estimation for Massive MIMO Systems
Orthogonal time frequency space (OTFS) modulation has the potential to enable robust communications in highly mobile scenarios. This is due to multiplexing information-bearing data into nearly-constant channels in the delay-Doppler domain instead of the time-frequency domain, which makes communication more resilient to fast changes in the channel....

Wireless Transmitter Identification in Visual Scenes
­Background Recent years have seen a growing interest in systems and technologies that rely on vision and wireless systems to provide certain capabilities. Examples include vision-aided wireless communications and wireless-vision activity recognition. However, these technologies have a common shortcoming; they do not directly address the association...

Relay-Aided Intelligent Reconfigurable Surfaces for Robust Performance with Fewer Elements
Background Wireless communications systems in 5G and beyond are using high-frequency signals (in the mmWave band in 5G and sub-terahertz bands in 6G and beyond). The large bandwidth available at these high frequencies enable the communication systems to send data at very high rates. However, increasing frequency comes at the expense of lower penetration...

Enabling Large Intelligent Surfaces Using Sparse Channel Sensors
Background Large Intelligent Surfaces (LISs) are envisioned as intrinsic components of beyond-5G wireless systems. In its core design concept, an LIS realizes a continuous electromagnetically-active surface by stacking a massive number of radiating/sensing elements. These elements interact with the incident signals, for example by reflecting them,...

Simultaneous Localization and Mapping by Merging Imaging and Wireless Communications
Background Simultaneous localization and mapping (SLAM) is the process by which a robot or system constructs a map of an undefined environment and tracks its location within it. By allowing autonomous agents to safely and independently navigate crowded settings, SLAM has found applications in virtual and augmented reality, driverless vehicles, and...
