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…
Ten Years of Research Advances in Full-Duplex Massive MIMO
Mohammadali Mohammadi, Zahra Mobini, Hien Quoc Ngo +1
We present an overview of ongoing research endeavors focused on in-band full-duplex (IBFD) massive multiple-input multiple-output (MIMO) systems and their applications. In response…
Energy Harvesting Characterization in Cell-Free Massive MIMO Using Markov Chains
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +1
This paper explores a discrete energy state transition model for energy harvesting (EH) in cell-free massive multiple-input multiple-output (CF-mMIMO) networks. Multiple-antenna ac…
Hybrid OTFS/OFDM Design in Massive MIMO
Ruoxi Chong, Mohammadali Mohammadi, Hien Quoc Ngo +2
We consider a downlink (DL) massive multiple-input multiple-output (MIMO) system, where different users have different mobility profiles. To support this system, we categorize the…
Next Generation Multiple Access with Cell-Free Massive MIMO
Mohammadali Mohammadi, Zahra Mobini, Hien Quoc Ngo +1
To meet the unprecedented mobile traffic demands of future wireless networks, a paradigm shift from conventional cellular networks to distributed communication systems is imperativ…
Phase-Shift and Transmit Power Optimization for RIS-Aided Massive MIMO SWIPT IoT Networks
Mohammadali Mohammadi, Hien Quoc Ngo, Michail Matthaiou
