The radio frequency (RF) front-end gain plays a crucial role since it determines the communication sensitivity and anti-interference performance, especially in the presence of both high-power interference signals and weak communication signals. In this paper, the influence of the RF front-end gain on communication sensitivity as well as Interference cancellation ratio (ICR) are thoroughly analyzed. Thereinafter, we derive the mathematical model of the RF front-end gain constrains taking communication sensitivity, ICR requirement and analog-to-digital converter quantization accuracy into consideration. Based on the upper and lower boundary region of gain, we propose the gain design criterion for adaptive interference cancellation in communication systems. Extensive simulations demonstrate that: 1) the ICR performance improves with the increase of RF front-end gain when lower than the gain obtained from upper boundary region, and is saturated afterward; 2) the gain obtained from lower boundary region analysis can ensure the communication sensitivity. Experimental results verify that the gain design criterion ensures the communication sensitivity and satisfies the requirements of anti-interference performance under high-power interference signals.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"7 ","pages":"1348-1362"},"PeriodicalIF":6.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11370903","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148487346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a quantum resilience trust architecture that couples probabilistic trust dynamics with hybrid post-quantum cryptography for real-time UAV–IoT coordination. At the edge, UAVs act as mobile trust agents that compute QRNG-driven interaction states and behavior vectors, combining task fidelity, entropy, and interaction history into structured descriptors that parameterize local trust. These descriptors are transformed at the fog layer by a Quantum Probabilistic Trust Model, which encodes trust as density matrices with non-commutative evidence operators, enabling order-sensitive updates and interference between heterogeneous trust cues. A Secure Trust Flow Algorithm then maps trust-state gradients and control signals to tri-level admission decisions (allow, defer, block) and feeds reinforcement updates back into the trust dynamics. A hybrid cryptographic engine integrates Kyber-based key encapsulation and Dilithium signatures with conditionally activated QKD, producing trust-aware session keys, adaptive rekeying, and post-quantum-secure channel authentication. A cloud-level ledger records PQC-protected trust trajectories and synthesizes time-varying trust maps that guide application governance, including flow prioritization, anomaly isolation, and cooperative route reconfiguration.

While substantial efforts have been invested in modeling and mitigating the nonlinear effect of power amplifiers (PAs), accurate modeling of the entire RF hardware component chain is missing. This paper addresses the various imperfections and impairments in RF transceivers, particularly within analog circuits, such as digital-to-analog-converter (DAC) nonlinear distortion, in-phase/quadrature-phase (IQ) imbalance, and PA nonlinearity. We introduce a Cascade Neural Network Digital Predistortion (Cascade-NNDPD) model to compensate for these impairments. The proposed model employs a two-stage neural network approach: the first stage utilizes a phase normalized time-delay neural network, termed PNTDNN for PA nonlinearities, while the second stage deploys an additional network (MLP, LSTM, BiLSTM, or GRU) to address remaining distortions. Our results demonstrate the potential of Cascade-NNDPD design in mitigating RF hardware impairments, thus enhancing the performance and reliability of wireless communications.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"7 ","pages":"1249-1262"},"PeriodicalIF":6.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11364127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148487429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The waveform, previously introduced as a robust low-rate design for wearable links, is here used as a testbed to study how sensing and communication capabilities diverge in ultra-low Signal-to-Noise Ratio (SNR) regimes. We specifically quantify the “breaking points” of the system, demonstrating that while the Walsh-coded communication link becomes unreliable around −18 dB, the direction finding (DF) capability persists with sub-degree accuracy (Root Mean Square Error RMSE <inline-formula> <tex-math>$lt ~1^{circ }$ </tex-math></inline-formula>) down to −33 dB.

Furthermore, we provide analytical approximations for the effective SNR and Angle-of-Arrival (AoA) Cramér-Rao Lower Bound (CRLB) under massive time-frequency averaging, and present a new comparative benchmark against standard estimators (Schmidl-Cox, Moose, MUSIC).

This paper shows that dense base station (BS) deployments produce multiple placements with identical cost, a phenomenon termed structural multi-optimality. A formal coverage-equivalence condition identifies when two BSs are interchangeable, and combinatorial bounds quantify the resulting solution multiplicity. Experiments on eight real BS datasets spanning three continents confirm that multi-optimality persists across four orders of magnitude of network density and is independent of the solver used. A demand-priority extension exploits this multiplicity by steering server selection toward high-demand BSs without increasing the server count. These results reframe MEC placement from a single-solution search into a landscape navigation problem, where planners can select among equivalent configurations to meet site-level and operational constraints.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"7 ","pages":"5889-5902"},"PeriodicalIF":6.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11541200","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148488398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop a stochastic model that captures weather-driven reliability, correlated repeater behavior, and multi-path reception, and formulate an optimization problem to minimize the expected communication delay. To address the intractability of this problem in large-scale, partially observable environments, we design a fully decentralized Multi-Agent Reinforcement Learning (MARL) framework based on Proximal Policy Optimization (PPO), where each satellite makes decisions using only local observations. The reward is aligned with the analytical delay objective, ensuring consistency between the model and learned policies.

Channel prediction using deep learning (DL) is essential in both bands to overcome these bands’ challenges, such as sensitivity to blockage. The existing prediction strategies assume static data distributions, where both training and testing datasets are derived from identical or highly similar environmental conditions. However, real-world conditions change over time due to non-stationarity in indoor wireless environments, resulting in data drift from differences between the train and test data distributions. Data drift can impact the generalization of DL channel prediction models by causing model drift. In this paper, the data drift in the mmWave and THz bands is categorized for the first time and represented in three scenarios: user densities, mobility stages, and room configurations. We investigate how data drift affects the generalization of DL models for mmWave and THz channel prediction, and propose a mitigation approach to address model drift and maintain generalization in affected scenarios. Our results show that mmWave models are most affected by mobility-stage changes, with performance degradation ranging from 11% to 68%, whereas THz models are most affected by user-density changes, with degradation ranging from 4% to 62%.

These slices can be tailored to specific services, user needs, and Quality-of-Service (QoS) requirements. However, most production-grade orchestration frameworks deployed today still rely on manually crafted templates and centralized controllers, even though a growing body of research has begun to explore deep reinforcement learning (DRL) and multi-agent DRL (MARL) for autonomous and distributed orchestration. As the number of slices increases, limited visibility across administrative domains and human-driven configuration render provisioning slow and error-prone. We address these limitations by proposing a multi-agent management framework where Large Language Models (LLMs) act as intelligent interfaces between tenants and the Management and Orchestration (MANO) stack. Agents interpret high-level intent provided by users or applications, translate it into standards-compliant descriptors, cooperate with other agents and underlying ML-based optimizers to allocate resources, and supervise the slice lifecycle. To validate this paradigm, we conduct two complementary experiments that together cover the AI-driven stages of the proposed workflow. First, we benchmark four state-of-the-art LLMs in generating Yet Another Markup Language (YAML)-based slice descriptions from natural-language prompts of varying complexity. GPT-4.1 consistently produces valid schemas and adheres to constraints, while other models occasionally violate conditions but still yield usable outputs. Second, we implement a proof-of-concept multi-agent system that, from a single user request, models a slice, synthesizes a Topology and Orchestration Specification for Cloud Applications (TOSCA) descriptor, and generates a deployment plan. This second experiment validates the multi-agent transformation chain from a slice request to deployable artifacts. The end-to-end workflow completes in about 40 seconds and produces artifacts validated by a domain expert. The final infrastructure instantiation of these already validated artifacts, e.g., through Kubernetes, Docker Compose, or NFV orchestration tools, is intentionally not treated as a separate AI experiment in this paper. Our results show that modern LLMs, when orchestrated in a collaborative agent framework, can significantly reduce the engineering effort and turnaround time required to move from high-level intents to deployable slice descriptors while ensuring alignment with industry standards. The proposed LLM-based framework can be integrated with any resource allocation optimizers or ML-based (e.g., DRL/MARL) infrastructure and network controllers for multi-tenant resource optimization.

The paper addresses quantum computing fundamentals and blockchain security implications, exploring quantum-resistant cryptographic schemes including lattice-based, hash-based, code-based, and multivariate approaches. Through systematic examination of post-quantum threats, this review shows vulnerabilities affecting nearly 25% of existing cryptocurrency assets, presenting how quantum computers can break public-key systems in polynomial time.
