Special Issue Information

Dear Colleagues,

This special issue highlights recent advances in applying artificial intelligence to signal processing and resource allocation in modern wireless networks. With the rapid evolution toward 6G and data-driven wireless environments, conventional communication and optimization techniques face growing limitations in scalability, adaptability, and efficiency. AI and machine learning have emerged as key enablers for addressing these challenges by providing intelligent, data-driven, and autonomous solutions.

The special issue presents innovative methodologies and system designs that leverage AI for enhanced channel estimation, interference management, beamforming, spectrum utilization, and resource scheduling. Contributions include learning-based physical layer techniques, reinforcement-learning-driven network control, energy-efficient and secure algorithmic strategies, and practical frameworks for real-time implementation. The topics of particular interest include, but are not limited to:

  • AI-enhanced physical-layer signal processing
  • Machine learning for channel estimation, prediction, and channel state feedback
  • Intelligent beamforming, precoding, and MIMO optimization
  • Deep learning-based modulation, detection, and decoding
  • Reinforcement learning for wireless resource allocation and scheduling
  • Federated, distributed, and edge learning architectures for wireless networks
  • Energy-efficient and green AI solutions for wireless systems
  • AI-driven interference management and power control
  • Joint communication, sensing, and computation resource optimization
  • Trustworthy, secure, and privacy-preserving AI for wireless networks
  • Digital twins and data-driven simulation platforms for wireless communications
  • AI-enabled mmWave, THz, RIS-assisted, and massive MIMO communications

I look forward to receiving your contributions.

To address the degradation in communication performance caused by the high mobility and dynamic uncertainty in vehicular network channels, this paper proposes a hybrid resource allocation framework that integrates the advantage actor–critic (A2C) algorithm with the multi-agent deep deterministic policy gradient (MADDPG) algorithm. By modeling the high-speed vehicular network environment, the resource allocation task is formulated as a multi-agent deep reinforcement learning (MADRL) problem within a continuous action space. The proposed framework leverages the advantage function to refine gradient estimation, thereby improving training stability and convergence behavior. Additionally, regularization penalty terms and constraint mechanisms are incorporated into the learning process to balance multiple communication objectives. Specifically, the method aims to maximize the throughput of vehicle-to-infrastructure (V2I) links while ensuring the transmission reliability of vehicle-to-vehicle (V2V) links. In simulation experiments, the proposed method performs better in terms of convergence. Compared with the conventional MADDPG algorithm, the average access success probability is improved by 1.6%, and the average V2I throughput increases by 3.5%, indicating a significant enhancement in overall vehicular communication efficiency and transmission performance.
