Demo: An RFSoC-Based Testbed for Over-the-Air Wireless Transceiver at Millimeter Wave Frequency
Jeet Tekchandani, Jai Mangal, Sumit J. Darak +1
The millimeter wave (mmW) frequency spectrum has been explored recently for large bandwidth communication. At these frequencies, narrow directional beams are required for communica…
Convergences for a Virus-like Evolving Population driven by Mutually-exciting Hawkes Processes
Rahul Roy, Dharmaraja Selvamuthu, Paola Tardelli
This paper presents a stochastic model motivated by the study of a virus-like evolving population with different mutation rates. This is a continuous time birth-death model: the bi…
Radar Sensing using Dual-Beam Reconfigurable Intelligent Surface
Kainat Yasmeen, Shobha Sundar Ram, Debidas Kundu
Around-the-corner radar sensing offers an opportunity for the radar to exploit multipath scattering along walls to detect targets beyond blockages. However, the radar detection per…
Around-the-corner Radar Sensing Using Reconfigurable Intelligent Surface
Kainat Yasmeen, Debidas Kundu, Shobha Sundar Ram
Around-the-corner radar (ACR) sensing of targets in non-line-of-sight (NLOS) conditions has been explored for security and surveillance applications and look-ahead warning systems…
Estimation of Electrical Characteristics of Complex Walls Using Deep Neural Networks
Kainat Yasmeen, Shobha Sundar Ram
Electromagnetic wave propagation through complex inhomogeneous walls introduces significant distortions to through-wall radar signatures. Estimation of wall thickness, dielectric,…
