This work presents an N×N scalable phased array architecture that supports simultaneous independent beams at X and Ku bands for 6G FR3 communications. The design is based on interleaved sparse subarra...
This paper presents an over-the-air post-distortion method that employs an embedded transmitting antenna to radiate a distortion-correcting waveform toward the intended user direction, enabling spatia...
We propose a V-band direct-RF digital-beamforming (DBF) receiver that employs a RF-input-free sampling-timing calibration method. This method controls phase difference between the LO signal of the sam...
This paper presents a low-power W-band chipset integrating four transmit (TX) channels and four receive (RX) channels, which supports a 30-GHz bandwidth for high-resolution frequency-modulated continu...
This work presents a high-throughput, fully digital SNN-based AMR system implemented on an FPGA, achieving a 320 MS/s input rate and latency of just 3.8 µs, with minimal hardware footprint. The design...
Frequency Modulated Continuous Wave (FMCW) radar enables privacy-preserving human activity recognition (HAR), and most existing approaches rely on time-Doppler (TD) and range-Doppler (RD) spectrograms...
We propose a physics-informed long-sequence Kalman filtering framework that leverages state-space neural architectures to model extended temporal structure beyond the limits of frame-by-frame filterin...
This paper presents a framework for multipath-robust in-air writing using two co-located D-band Frequency-Modulated Continuous-Wave (FMCW) radar sensors. While millimeter-wave radar offers privacy-pre...
Technologies for sensing and monitoring human-related activities and vehicles/objects are an important and increasing part of urban management and safety. It is desirable to enable these systems to op...
Reconfigurable intelligent surfaces (RISs) mitigate non-line-of-sight challenges but remain limited in 5G systems due to poor scalability and the absence of integrated user localization needed for low...
