Multi-view imaging in networked sensing systems: A covariance-based approach
Junyuan Gao, Weifeng Zhu, Yanmo Hu +5
This paper considers multi-view imaging in a sixth-generation (6G) integrated sensing and communication network, which consists of a transmit base-station (BS), multiple receive BS…
Integrated Massive Communication and Target Localization in 6G Cell-Free Networks
Junyuan Gao, Weifeng Zhu, Shuowen Zhang +4
This paper presents an initial investigation into the combination of integrated sensing and communication (ISAC) and massive communication, both of which are largely regarded as ke…
Flat-Top Beamforming with Efficient Array-Fed RIS
Krishan Kumar Tiwari, Giuseppe Caire
Flat-top beam designs are essential for uniform power distribution over a wide angular sector for applications such as 5G/6G networks, beaconing, satellite communications, radar sy…
Array-Fed RIS: Validation of Friis-Based Modeling Using Full-Wave Simulations
Krishan Kumar Tiwari, Thomas Flisgen, Wolfgang Heinrich +1
Space-fed large antenna arrays offer superior efficiency, simplicity, and reductions in size, weight, power, and cost (SWaP-C) compared to constrained-feed systems. Historically, h…
A Modular Pragmatic Architecture for Multiuser MIMO with Array-Fed RIS
Krishan Kumar Tiwari, Giuseppe Caire
We propose a power- and hardware-efficient, pragmatic, modular, multiuser/multibeam array-fed RIS architecture particularly suited to operate in very high frequency bands (high mmW…
