Special Issue Information

Dear Colleagues,

The fifth generation (5G) of mobile communications has helped to bridge the growth of data and device connections demand. This Special Issue entitled ”Second Edition of Advances in Wireless Communications Systems” aims to investigate the new challenges and opportunities which will be enabled by the sixth generation (6G) of mobile communications.

The next network protocols should take account of resource allocation and optimization, also provided by new artificial intelligence algorithms or Fog computing and networking systems. Moreover, massive data transmission should require a high level of cybersecurity, including physical layer security. Finally, to satisfy the new network performance demand, updated spectral bands in radio and optical frequencies are required.

Papers should highlight either theoretical issues or practical applications, such as smart cities with ultra-low latency communications, healthcare with massive density of wireless body area networks (WBANs), the Internet of Things with ultra-low power communications, infotainment with high throughput for ultra-high multimedia definition, etc.

The contribution topics of primary interest include, but are not limited to:

  • Network protocols;
  • Resource allocation techniques;
  • Artificial intelligence applied in communications systems;
  • Radio Frequencies (RFs) enabling 6G;
  • Optical wireless communications;
  • Vehicular communications;
  • Industrial communications;
  • Wireless body area networks (WBANs);
  • Ultra-low power communications;
  • Network performance;
  • Fog computing and networking;
  • Pervasive communications;
  • 6G communications;
  • Physical layer security;
  • Cybersecurity systems.

Complexity of non-orthogonal multiple access (NOMA) digital signal processing schemes is particularly relevant in mobile environments because of the varying channel conditions of every single user. In contrast to legacy modulation and coding schemes (MCSs), NOMA MCSs typically have irregular symbol constellations with asymmetric symbol decision regions affecting synchronization at the receiver. Research papers investigating signal processing in this emerging field usually lack sufficient details for facilitating software-defined radio (SDR) implementation. This work presents a new symbolic framework approach for simulating signal processing functions in SDR transmit–receive paths in a dynamic NOMA downlink use case. The proposed framework facilitates simple and intuitive implementation and testing of NOMA schemes and can be easily expanded and implemented on commercially available SDR hardware. We explicitly address several important design and measurement parameters and their relationship to different tasks, including variable constellation processing, carrier and symbol synchronization, and pulse shaping, focusing on quadrature amplitude modulation (QAM). The advantages of the proposed approach include intuitive symbolic modeling in a dynamic framework for NOMA signals; efficient, more accurate, and less time-consuming design flow; and generation of synthetic training data for machine-learning models that could be used for system optimization in real-world use cases.

This study proposes a novel optical wireless communication system for high-speed, large-capacity data transmission, supporting underwater IoT devices in shallow seas. The system employs a mirror-equipped aerial drone as a relay between underwater drones and a terrestrial station, using 850 nm optical signals for low atmospheric loss and enhanced confidentiality. Adaptive modulation optimizes transmission capacity based on SNR, accounting for air and underwater channel characteristics. Experiments confirmed an exponential SNR decrease with distance (0.6–1.8 m) and demonstrated successful 4K UHD video streaming in shallow seawater (turbidity: 2.2 NTU) without quality loss. The design ensures cost-effectiveness and stable optical alignment using advanced posture control. Full article
