Future cellular networks aim to integrate sensing with communication, leveraging beamforming in the millimeter wave (mmWave) band for its enhanced spatial multiplexing. In this paper, we present CHAME...
The relative proximity of the 24 GHz ISM band and the 5G FR2 band offers promising opportunities for Integrated Sensing and Communication (ISAC) operations leveraging directional transmission/receptio...
We present the design, implementation, and experimental validation of a millimeter-wave (mmWave) integrated sensing and communication (ISAC) hardware testbed. Our contribution includes the algorithms ...
This paper proposes a low-power and self-interference-tolerant receiver for shared-aperture in-band full-duplex arrays. A transformer using an asymmetric center-tap configuration provides high common-...
In this paper, we present an investigation of a fully passive positioning system based on radiometric measurements. The proposed technology enables passive Direction-of-Arrival (DoA) estimation of hum...
This paper presents a spectrum-agile 60 GHz cognitive radio architecture that achieves a 94% reduction in idle power consumption via a hierarchical wake-up strategy. The system dynamically scales from...
This paper demonstrates a correlation-based RF front-end approach that leverages pump-modulated parametric frequency conversion to enable continuous-time, waveform-selective signal processing. By trea...
This paper presents the first demonstration of a W-band high-output-power direct digital RF transmitter using a Manchester (MAN)-encoded 1-bit band-pass delta-sigma modulator (BPDSM) and a frequency t...
This paper presents an E-band 2×2 unit phased array with stitching scalability from die-to-die up to reticle-to-reticle for wafer-scale phased-array systems, implemented in 28-nm CMOS technology. The ...
This paper presents a compact D-band time-division-duplex (TDD) front-end in 130-nm SiGe BiCMOS. The design features a novel, ultra-compact asymmetric T/R switch based on a reconfigurable tri-conducto...
