• Distributed Physical Layer Authentication and Collaborative RSMA in Non-Terrestrial Networks via Graph Reinforcement Learning

  Parsa Rajabi, Mohammad Mirzaee, Mohammad Reza Abedi, Nader Mokari, Paeiz Azmi · 10 September 2026

  Existing physical-layer authentication (PLA) schemes for non-terrestrial networks (NTNs) often rely on single-anchor verification, lack joint authentication-transmission design, and ignore tag privacy leakage under eavesdropping. In this paper, we consider passive, location-aware, static eavesdroppe…

• Rate-Distortion-Perception Theory: Redefining the Fundamental Limits of Information Representation

  Photios A. Stavrou, Giuseppe Serra, Marios Kountouris · 21 July 2026

  Classical rate-distortion (RD) theory has long established the fundamental limits of lossy compression by quantifying the minimum number of bits required to represent a source under a prescribed distortion constraint. However, widely used distortion measures such as mean-squared error often fail to …

• Tight Sample Bounds for Renyi and Min-Entropy Estimation

  Arman Adibi, Piotr Krysta · 21 July 2026

  Estimating entropy from samples is fundamental in information theory and property testing. Shannon entropy measures average uncertainty and can be estimated to constant additive accuracy over a $k$-symbol alphabet using $\Theta(k/\log k)$ samples. Min-entropy depends only on the most likely symbol. …

• 6G Sensing Security: Distributed Game-Theoretic RL for Urban Beamforming and Attacker Detection

  Parmida Geranmayeh, Onur G\"unl\"u · 8 July 2026

  In next-generation networks, communication systems will no longer be limited to data transmission and will be expected to acquire awareness of the surrounding environment. This leads to the concept of integrated sensing and communication (ISAC), where the same wireless infrastructure is used for bot…

• Semantic Leakage and Privacy Preservation in Relay-Assisted Semantic Communications

  Yalin E. Sagduyu, Tugba Erpek, Aylin Yener, Sennur Ulukus · 1 July 2026

  Semantic communication (SemCom) has emerged as a promising paradigm in which the transmission of task-relevant information is prioritized over raw data, enabling efficient and robust communication under resource and channel constraints. In this paper, the privacy implications of relay-assisted SemCo…

• Semantic-Aware Generative Image Transmission for Resource-Constrained Visual IoT Systems

  Chenyang Zhang, Changwang Liu, Jinqi Zhu, Jiayi Chang, Yuxuan Wang, Shuqing He, Jia Guo · 25 June 2026

  Resource-constrained visual Internet of Things (IoT) systems, such as edge cameras, unmanned sensing platforms, industrial inspection nodes, and remote monitoring sensors, often need to transmit task-relevant visual evidence over low-rate wireless links to an edge/cloud service. Existing image commu…

• Minimum Distortion Quantization with Specified Output Distribution

  Aolin Xu · 10 June 2026

  We derive the optimal quantizer of a real-valued random variable $W$ with distribution $P_W$ such that 1) the distribution of the quantization output $X$ that can take $k$ values follows any specified distribution $P_X$ over $\{1,\ldots,k\}$, and 2) the minimum mean squared error (MMSE) of estimatin…

• Lost and Found in Translation: Variational Diagnostics for Neural Codebook Channels

  Yusuke Hayashi · 20 May 2026

  Classical communication systems fail not only through random noise but also when transmitter and receiver use incompatible operational codebooks. Variational autoencoders (VAEs) train an encoder $q_\phi$ and decoder $p_\theta$ jointly, and practitioners treat the resulting latent space as a discrete…

• Feedback Lunch: Learned Feedback Codes for Secure Communications

  Yingyao Zhou, Natasha Devroye, Onur G\"unl\"u · 4 May 2026

  We consider reversely-degraded secure-communication channels, for which the secrecy capacity is zero if there is no channel feedback. Specifically, we focus on a seeded modular code design for the block-fading Gaussian wiretap channel with channel-output feedback, combining universal hash functions …

• Secure Rate-Distortion-Perception: A Randomized Distributed Function Computation Approach for Realism

  Gustaf Åhlgren, Onur Günlü · 23 April 2026

  Fundamental rate-distortion-perception (RDP) trade-offs arise in applications requiring maintained perceptual quality of reconstructed data, such as neural image compression. When compressed data is transmitted over public communication channels, security risks emerge. We therefore study secure RDP …

• Channel Prediction-Based Physical Layer Authentication under Consecutive Spoofing Attacks

  Yijia Guo, Junqing Zhang, Yao-Win Peter Hong · 23 March 2026

  Wireless networks are highly vulnerable to spoofing attacks, especially when attackers transmit consecutive spoofing packets. Conventional physical layer authentication (PLA) methods have mostly focused on single-packet spoofing attack. However, under consecutive spoofing attacks, they become ineffe…

• Model-Aware Rate-Distortion Limits for Task-Oriented Source Coding

  Andriy Enttsel, Vincent Corlay · 16 February 2026

  Task-Oriented Source Coding (TOSC) has emerged as a paradigm for efficient visual data communication in machine-centric inference systems, where bitrate, latency, and task performance must be jointly optimized under resource constraints. While recent works have proposed rate-distortion bounds for co…

• V2X-DSC: Multi-Agent Collaborative Perception with Distributed Source Coding Guided Communication

  Yuankun Zeng, Shaohui Li, Zhi Li, Shulan Ruan, Yu Liu, You He · 3 February 2026

  Collaborative perception improves 3D understanding by fusing multi-agent observations, yet intermediate-feature sharing faces strict bandwidth constraints as dense BEV features saturate V2X links. We observe that collaborators view the same physical world, making their features strongly correlated; …

• AmbShield: Enhancing Physical Layer Security with Ambient Backscatter Devices against Eavesdroppers

  Yifan Zhang, Yishan Yang, Riku J\"antti, Zheng Yan, Dusit Niyato, Zhu Han · 16 January 2026

  Passive eavesdropping compromises confidentiality in wireless networks, especially in resource-constrained environments where heavyweight cryptography is impractical. Physical layer security (PLS) exploits channel randomness and spatial selectivity to confine information to an intended receiver with…

• Hierarchical Secure Aggregation with Heterogeneous Security Constraints and Arbitrary User Collusion

  Zhou Li, Xiang Zhang, Jiawen Lv, Jihao Fan, Haiqiang Chen, Giuseppe Caire · 13 January 2026

  In hierarchical secure aggregation (HSA), a server communicates with clustered users through an intermediate layer of relays to compute the sum of users' inputs under two security requirements -- server security and relay security. Server security requires that the server learns nothing beyond the d…

• Joint Link Adaptation and Device Scheduling Approach for URLLC Industrial IoT Network: A DRL-based Method with Bayesian Optimization

  Wei Gao, Paul Zheng, Peng Wu, Yulin Hu, Anke Schmeink · 30 December 2025

  In this article, we consider an industrial internet of things (IIoT) network supporting multi-device dynamic ultra-reliable low-latency communication (URLLC) while the channel state information (CSI) is imperfect. A joint link adaptation (LA) and device scheduling (including the order) design is pro…

• Adversarial Jamming for Autoencoder Distribution Matching

  Waleed El-Geresy, Deniz G\"und\"uz · 3 December 2025

  We propose the use of adversarial wireless jamming to regularise the latent space of an autoencoder to match a diagonal Gaussian distribution. We consider the minimisation of a mean squared error distortion, where a jammer attempts to disrupt the recovery of a Gaussian source encoded and transmitted…

• Latency and Ordering Effects in Online Decisions

  Duo Yi · 18 November 2025

  Online decision systems routinely operate under delayed feedback and order-sensitive (noncommutative) dynamics: actions affect which observations arrive, and in what sequence. Taking a Bregman divergence $D_\Phi$ as the loss benchmark, we prove that the excess benchmark loss admits a structured lowe…
