Special Issue Information

Dear Colleagues,

Visible Light Communication (VLC) is an evolving field complementing traditional communication and positioning technologies. This Special Issue delves into VLC's multifaceted aspects, from theoretical foundations to practical applications in next-generation communication systems and precision indoor positioning.

Our aim is to enhance positioning and communication precision through algorithmic innovation and system design advancements. With developments in LEDs and photovoltaic devices, we foresee cost-effective, widespread communication systems for everyday applications. We address the challenges of integrating VLC with existing infrastructures and mitigating interference in complex settings.

Despite technological progress, research challenges remain. We explore interdisciplinary VLC topics, including protocol design for indoor positioning, VLC advancements for IoT, smart buildings, vehicular networks, and the security and efficiency of these technologies.

We invite original research articles and reviews on the following topics:

  • VLC channel modeling and estimation;
  • Channel characterization and VLC-specific encoding;
  • Efficient signal processing for high-precision visible light positioning;
  • Security, standards, and normalization in VLC;
  • Recent developments in VLC geolocation and communication.

This Special Issue aims to provide a comprehensive collection for researchers, engineers, and practitioners, offering an integrated perspective on the current and future advancements in VLC-based communications and geolocation.

We explore the use of smartphones to decode data transmitted from LEDs to smartphone cameras in visible light communication (VLC) applied to indoor positioning applications. The LEDs—modified to enable rapid on-off keying—transmit identification codes or optically encoded location data imperceptible to human perception. Equipped with a camera, the smartphone employs a single framed image to detect the presence of the luminaires in the image, decode their transmitted identifiers or locations, and determine the smartphone’s position and orientation relative to the luminaires. The camera captures and processes images continuously. The following fundamental issues are addressed in this research: (i) analyzing the camera parameters on smartphones that affect data decoding results; (ii) exploiting the rolling shutter effect of the CMOS image sensor to receive multiple bits of data encoded in the optical communication line with a single frame shot; (iii) advancing research in developing algorithms to process data from multiple LEDs simultaneously. We conduct experiments to evaluate and analyze feasibility, as well as the challenges of the design, through scenarios varying in distance, transmission frequency, and data length. Full article
