Near-Field Energy Harvesting Using XL-MIMO Over Non-Stationary Channels
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +1
This paper explores the maximization of the harvested power efficiency (HPE) in a modular extremely large multiple-input multiple-output (XL-MIMO) system, which supports energy har…
Near-Field SWIPT Using XL-MIMO: Power Allocation and Subarray Activation
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +1
This paper investigates the simultaneous wireless information and power transfer (SWIPT) capability of a modular extremely large multiple-input multiple-output (XL-MIMO) system, in…
Fronthaul-Aware User-Centric Generalized Cell-Free Massive MIMO Systems
Zahra Mobini, Ahmet Hasim Gokceoglu, Li Wang +2
We consider fronthaul-limited generalized zeroforcing-based cell-free massive multiple-input multiple-output (CF-mMIMO) systems with multiple-antenna users and multipleantenna acce…
Cell-Free Full-Duplex Communication -- An Overview
Diluka Galappaththige, Mohammadali Mohammadi, Hien Quoc Ngo +2
Cell-free (CF) architecture and full-duplex (FD) communication are leading candidates for next-generation wireless networks. The CF framework removes cell boundaries in traditional…
Multi-Static Cell-Free Massive MIMO ISAC: Performance Analysis and Power Allocation
Nhan Thanh Nguyen, Tianyu Fang, Hien Quoc Ngo +1
In this work, we consider a cell-free massive multiple-input multiple-output (MIMO) integarted sensing and communications (ISAC) system with maximum-ratio transmission schemes comb…
Distributed Graph Neural Network Design for Sum Ergodic Spectral Efficiency Maximization in Cell-Free Massive MIMO
Nguyen Xuan Tung, Trinh Van Chien, Hien Quoc Ngo +1
This paper proposes a distributed learning-based framework to tackle the sum ergodic rate maximization problem in cell-free massive multiple-input multiple-output (MIMO) systems by…
