Special Issue Information

Dear Colleagues,

The research on integrated sensing and communications has drawn ever increasing attention in both academia and industry. Exploiting the sensing capability of electromagnetic waves, such as optical wireless signals, visible light signals, and radio frequency signals, the performance of communication and networking can be improved. On the other hand, more knowledge and better performance of sensing, positioning, target detection, and recognition can be achieved through properly designed wireless and/or optical communications. The integration of sensing and communications is becoming a hot trend towards next-generation information and communication networks, bringing lots of opportunities for new theories, technologies, and applications. Thus, this Special Issue is soliciting new research works and practical applications, as well as review surveys, in the area of cutting-edge techniques and applications of integrated sensing and communications (ISAC) using wireless and/or optical signals. The topics of interest include, but are not limited to:

  • Fundamental theory for wireless/optical ISAC;
  • Channel characterization and modelling for wireless/optical ISAC;
  • Transmitters and receiver design and technologies for wireless/optical ISAC;
  • Localization and navigation using wireless/optical signals;
  • Target sensing, detection, and recognition using wireless/optical signals;
  • Cooperative and intelligent communications and networking aided by sensing;
  • Artificial intelligence-enabled ISAC approaches;
  • Visible light communications and positioning;
  • Underwater optical wireless communications;
  • Underwater target detection and navigation;
  • New architecture and framework of wireless/optical ISAC;
  • New applications and scenarios of wireless/optical ISAC;
  • Field tests and experimental results of ISAC systems.

Visible light communication (VLC) aided by unmanned aerial vehicles (UAVs) offers significant advantages in adapting to dynamic network requirements, but the endurance and service capability of UAVs are still the key limiting factors. To overcome this limitation, the UAV array-aided VLC system with an enhanced angle diversity transmitter (ADT) is proposed to improve energy efficiency (EE). Enhanced ADTs with varying LED layers, multiple LEDs per layer, and inter-layer rotation angles are considered. By jointly optimizing the inclination angle of the side LEDs in the enhanced ADT and the hovering height of the UAVs, this research aims to minimize the power consumption of the UAV array-aided VLC system while meeting illumination and communication requirements. The simulation results present that the EE of the centralized single-UAV VLC system can be greatly improved by applying the enhanced ADT structures. More specifically, compared with the single LED transmitter configuration, an EE enhancement of up to 215.7% can be achieved by the enhanced ADT, which employs multi-layer LEDs, inter-layer rotation, and layer-doubled designs. In addition, the EE can be further improved by the deployment of a distributed UAV array. The VLC system with four UAVs is demonstrated to achieve a peak EE performance of 19.9 bits/J/Hz, representing a 298% improvement over the centralized single-UAV configuration. Full article

Visiblelightcommunication (VLC) is an emerging technology that offers an alternative to traditional wireless communications systems. However, the technology presents limitations related to the impact of the receiver’s orientation, which can significantly impact its performance. To address this issue, VLC systems use diversity schemes, such as transmitter and receiver diversity. In this paper, we derive an analytical expression for the probability of maintaining a line-of-sight (LoS) link in an underground mining visible light communication (UM-VLC) system with a receiver embedded in an object, such as a helmet, by considering user mobility. We show that the angle of incidence depends on the distance from the source and derive the probability accordingly for single-input single-output (SISO), multiple-input single-output (MISO), and single-input multiple-output cases (SIMO). Our results show that the analytical results fit with the simulated results. Furthermore, the resulting probabilities show that the angular position of the receiver significantly affects the channel’s quality, with the optimal position dependent on the field-of-view characteristics. These findings can provide an appropriate framework for receiver and transmitter diversity design through analytical expression. Full article
