RIS-Assisted XL-MIMO for Near-Field and Far-Field Communications
Xiaomin Cao, Mohammadali Mohammadi, Hien Quoc Ngo +2
We consider a reconfigurable intelligent surface (RIS)-assisted extremely large-scale multiple-input multiple-output (XL-MIMO) downlink system, where an XL-MIMO array serves two gr…
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…
Active and Passive Beamforming Designs for SER Minimization in RIS-Assisted MIMO Systems
Trinh Van Chien, Bui Trong Duc, Ho Viet Duc Luong +3
This research exploits the applications of reconfigurable intelligent surface (RIS)-assisted multiple input multiple output (MIMO) systems, specifically addressing the enhancement…
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…
Ubiquitous Cell-Free Massive MIMO Communications
Giovanni Interdonato, Emil Björnson, Hien Quoc Ngo +2
Since the first cellular networks were trialled in the 1970s, we have witnessed an incredible wireless revolution. From 1G to 4G, the massive traffic growth has been managed by a c…
