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…
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…
