Litter-Masked Block z-Channel: Designing Cover Distributions Against Public-Design Observers
Bin Han, Wenwen Chen, Yao Zhu +3
Networking defenses against traffic analysis fill idle slots with cover traffic, yet the physical layer carrying it still hands upper layers the erasure-only model of a silent-idle…
Confusion-Erasure Bounds of Error-Bounded Decoders under QAM
Wenwen Chen, Bin Han, Hans D. Schotten
6G is expected to push ultra-reliable low-latency communication (URLLC) toward stringent residual-error targets for mission-critical services, where undetected errors and erasures…
Symbol-Domain Chase Combining on Fourier-Curve Constellations: Exact Identities and Penalties of Per-Round Bit Reduction
Bin Han, Muxia Sun, Hans D. Schotten
A Fourier-curve constellation adds artificial noise along the tangent at the transmitted symbol, giving each symbol candidate its own rank-one noise covariance. A Chase retransmiss…
Generative Semantic HARQ: Latent-Space Text Retransmission and Combining
Bin Han, Yulin Hu, Hans D. Schotten
Semantic communication conveys meaning rather than raw bits, but reliability at the semantic level remains an open challenge. We propose a semantic-level hybrid automatic repeat re…
Confusions and Erasures of Error-Bounded Block Decoders with Finite Blocklength
Bin Han, Yao Zhu, Rafael F. Schaefer +4
This paper investigates two distinct types of block errors - undetected errors (confusions) and erasures - in additive white Gaussian noise (AWGN) channels with error-bounded block…
Joint Optimization for Security and Reliability in Round-Trip Transmissions for URLLC services
Xinyan Le, Yao Zhu, Yulin Hu +1
Physical layer security (PLS) is a potential solution for secure and reliable transmissions in future Ultra-Reliable and Low-Latency Communications (URLLC). This work jointly optim…
Physical Layer Deception as a Stackelberg Game: Strategy Regimes, Equilibrium, and Robust Design
Wenwen Chen, Bin Han, Yao Zhu +3
Physical layer deception (PLD) combines physical layer security (PLS) with deception: the transmitter actively misleads the eavesdropper with falsified information. We model the tr…
Physical Layer Deception in OFDM Systems
Wenwen Chen, Bin Han, Yao Zhu +2
As a promising technology, physical layer security (PLS) enhances security by leveraging the physical characteristics of communication channels. However, it commonly takes the legi…
A Semantic Model for Physical Layer Deception
Bin Han, Yao Zhu, Anke Schmeink +2
Physical layer deception (PLD) is a novel security mechanism that combines physical layer security (PLS) with deception technologies to actively defend against eavesdroppers. In th…
Physical Layer Deception with Non-Orthogonal Multiplexing
Wenwen Chen, Bin Han, Yao Zhu +3
Physical layer security (PLS) is a promising technology to secure wireless communications by exploiting the physical properties of the wireless channel. However, the passive nature…
Fairness-aware Age-of-Information Minimization in WPT-Assisted Short-Packet Data Collection for mURLLC
Yao Zhu, Xiaopeng Yuan, Yulin Hu +4
The technological landscape is rapidly evolving toward large-scale systems. Networks supporting massive connectivity through numerous Internet of Things (IoT) devices are at the fo…
