Sparse Principal Component Analysis with Energy Profile Dependent Sample Complexity
Mengchu Xu, Jian Wang, Yonina C. Eldar
We study sparse principal component analysis in the high-dimensional, sample-limited regime, aiming to recover a leading component supported on a few coordinates. Despite extensive…
Task-Based Quantization for Channel Estimation in RIS Empowered MmWave Systems
Gyoseung Lee, In-soo Kim, Yonina C. Eldar +4
In this paper, we investigate channel estimation for reconfigurable intelligent surface (RIS) empowered millimeter-wave (mmWave) multi-user single-input multiple-output communicati…
Polarization Aware Movable Antenna
Runxin Zhang, Yulin Shao, Yonina C. Eldar
This paper presents a polarization-aware movable antenna (PAMA) framework that integrates polarization effects into the design and optimization of movable antennas (MAs). While MAs…
Sensing With Communication Signals: From Information Theory to Signal Processing
Fan Liu, Ya-Feng Liu, Yuanhao Cui +6
The Integrated Sensing and Communications (ISAC) paradigm is anticipated to be a cornerstone of the upcoming 6G networks. In order to optimize the use of wireless resources, 6G ISA…
A MIMO ISAC System for Ultra-Reliable and Low-Latency Communications
Homa Nikbakht, Yonina C. Eldar, H. Vincent Poor
In this paper, we propose a bi-static multiple-input multiple-output (MIMO) integrated sensing and communication (ISAC) system to detect the arrival of ultra-reliable and low-laten…
Decentralized MIMO Systems with Imperfect CSI using LMMSE Receivers
Zeyan Zhuang, Xin Zhang, Dongfang Xu +2
Centralized baseband processing (CBP) is required to achieve the full potential of massive multiple-input multiple-output (MIMO) systems. However, due to the large number of antenn…
