Beyond the Matrix Sign: Quadratic Spectral Descent
Qiaozhe Zhang, Jun Sun, Yingzhuang Liu
Muon emerges as a strong competitor of the AdamW for LLM pretraining, because the matrix-wise update it employs can potentially incur smaller second-order penalty than the once dom…
CMT-Aware Channel Modeling and Transmit-Power Minimization for Pinching-Antenna Systems
Chuang Luo, Gui Zhou, Vasilis K. Papanikolaou +2
This letter investigates transmit-power minimization for multiuser pinching-antenna system (PAS) from a coupled-mode-theory (CMT)-aware perspective. Existing CMT-based pinching ant…
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…
Digital Self-Interference Cancellation in Full-Duplex Radios: A Fundamental Limit Perspective
Limin Liao, Jun Sun, Junzhi Wang +4
D-SIC is of crucial importance for the implementation of IBFD radios. Unfortunately, the achievable performance limit remains underexplored. To fill this gap, in this paper we aim…
