Over-the-Air Interference Nulling Using Passive RIS for Two-Way K-User Interference Channel
Junzhi Wang, Jun Sun, Limin Liao +2
Interference constitutes the fundamental performance bottleneck in wireless networks. Meanwhile, reconfigurable intelligent surface (RIS) has emerged as a promising technique for i…
Over-the-Air Interference Nulling Using Active RIS
Junzhi Wang, Jun Sun, Limin Liao +2
Interference fundamentally limits the performance of dense wireless networks, and reconfigurable intelligent surfaces (RIS) have recently emerged as a promising means of enabling i…
Achieving Interference-Free Degrees of Freedom in Cellular Networks via RIS
Junzhi Wang, Jun Sun, Zheng Xiao +2
It's widely perceived that Reconfigurable Intelligent Surfaces (RIS) cannot increase Degrees of Freedom (DoF) due to their relay nature. A notable exception is Jiang \& Yu's work.…
Addressing the curse of mobility in massive MIMO with Prony-based angular-delay domain channel predictions
Haifan Yin, Haiquan Wang, Yingzhuang Liu +1
Massive MIMO is widely touted as an enabling technology for 5th generation (5G) mobile communications and beyond. On paper, the large excess of base station (BS) antennas promises…
The Impact of Physical Channel on Performance of Subspace-Based Channel Estimation in Massive MIMO Systems
Mohammed Teeti, Jun Sun, David Gesbert +1
A subspace method for channel estimation has been recently proposed [1] for tackling the pilot contamination effect, which is regarded by some researchers as a bottleneck in massiv…
A Coordinated Approach to Channel Estimation in Large-scale Multiple-antenna Systems
Haifan Yin, David Gesbert, Miltiades Filippou +1
This paper addresses the problem of channel estimation in multi-cell interference-limited cellular networks. We consider systems employing multiple antennas and are interested in b…
