Deep learning has significantly improved the performance of fingerprint liveness detection, while susceptibility to adversarial attacks remains a critical security challenge. Existing input transformation–based defense methods, including JPEG compression, total variance minimization (TVM), high‐level representation guided denoiser (HGD), and Defed, are

Robust Spectral and Energy Efficiency Tradeoff for RIS‐Aided Multi‐User Communication
In this work, an RIS‐aided multi‐user network with imperfect CSI is investigated. Correspondingly, we focus on balancing SE and EE through the collaborative design of the base station (BS)'s precoding matrix and the RIS's phase shifts, which consider the transmit power budget and the channel uncertainties constraints.

This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...

Construction‐Free Polar Coding For Practical Entropy Coding Tasks
A novel construction‐free polar coding technique is proposed for practical data compression applications. ABSTRACT This paper explores the practical application of source polar codes to entropy coding tasks in modern transform coding pipelines. Transform coding remains the predominant and rapidly evolving framework for compressing complex real‐world ...
