Dynamic Metasurface Antenna (DMA) is a cutting-edge antenna technology offering scalable and sustainable solutions for large antenna arrays. The effectiveness of DMAs stems from th…
Time-Domain Channel Estimation for Extremely Large MIMO THz Communication Systems Under Dual-Wideband Fading Conditions
Evangelos Vlachos, Aryan Kaushik, Yonina C. Eldar +1
In this paper, we study the problem of extremely large (XL) multiple-input multiple-output (MIMO) channel estimation in the terahertz (THz) frequency band, considering the presence…
Near-Field 3D Localization via MIMO Radar: Cramér-Rao Bound Analysis and Estimator Design
Haocheng Hua, Jie Xu, Yonina C. Eldar
This paper studies a near-field multiple-input multiple-output (MIMO) radar sensing system, in which the transceivers with massive antennas aim to localize multiple near-field targ…
Unfolding for Joint Channel Estimation and Symbol Detection in MIMO Communication Systems
Swati Bhattacharya, K. V. S. Hari, Yonina C. Eldar
This paper proposes a Joint Channel Estimation and Symbol Detection (JED) scheme for Multiple-Input Multiple-Output (MIMO) wireless communication systems. Our proposed method for J…
Robust Transceiver Design for Covert Integrated Sensing and Communications With Imperfect CSI
Yuchen Zhang, Wanli Ni, Jianquan Wang +4
We propose a robust transceiver design for a covert integrated sensing and communications (ISAC) system with imperfect channel state information (CSI). Considering both bounded and…
RIS-Aided Index Modulation with Greedy Detection over Rician Fading Channels
Aritra Basu, Soumya P. Dash, Aryan Kaushik +3
