A metamaterial (MTM)-based thin planar lens antenna is proposed for spatial beamforming
and multibeam massive multiple-input multiple-output systems. The antenna consists of a …

The research on Wi-Fi sensing has been thriving over the past decade but the process has
not been smooth. Three barriers always hamper the research: 1) unknown baseband design …

Due to the severe multipath effect, no satisfactory device-free methods have ever been
found for indoor speed estimation problem, especially in non-line-of-sight (LOS) scenarios …

Motion detection acts as a key component for a range of applications such as home security,
occupancy and activity monitoring, retail analytics, etc. Most existing solutions, however …

In this work, we develop DeepWiPHY, a deep learning-based architecture to replace the
channel estimation, common phase error (CPE) correction, sampling rate offset (SRO) …

Child presence detection (CPD) is becoming a regulatory requirement for car manufacturers
to save children's lives when they are left alone in unattended vehicles. However, most of …

In this article, pseudorandom noise (PN) sequence time-modulated reflective metasurfaces
are proposed to provide a low-cost, low-complexity, simple solution for target recognition. By …

This work presents an improved method of 3D mesh models indexing for content-based
retrieval in database with shape similarity and appearance queries. The approach is based …

This paper demonstrates the implementation of a space–frequency line coded-orthogonal
frequency-division multiplexing (SFLC-OFDM) system. The SFLC-OFDM system utilizes …
