Digital Self-Interference Cancellation in Full-Duplex Radios: A Fundamental Limit Perspective
Limin Liao, Jun Sun, Junzhi Wang +4
Digital self-interference cancellation (D-SIC) plays a crucial role in in-band full-duplex radios. Unfortunately, its fundamental limit remains unclear. In this paper, we aim to ad…
How Sparse Can We Prune A Deep Network: A Fundamental Limit Perspective
Qiaozhe Zhang, Ruijie Zhang, Jun Sun +1
Network pruning is a commonly used measure to alleviate the storage and computational burden of deep neural networks. However, the fundamental limit of network pruning is still lac…
Rényi Sharpness: A Novel Sharpness that Strongly Correlates with Generalization
Qiaozhe Zhang, Jun Sun, Ruijie Zhang +1
Sharpness (of the loss minima) is widely believed to be a good indicator of generalization of neural networks. Unfortunately, the correlation between existing sharpness measures an…
Analog Self-Interference Cancellation in Full-Duplex Radios: A Fundamental Limit Perspective
Limin Liao, Jun Sun, Junzhi Wang +1
Analog self-interference cancellation (A-SIC) plays a crucial role in the implementation of in-band full-duplex (IBFD) radios, due to the fact that the inherent transmit (Tx) noise…
