Special Issue Information

Dear Colleagues,

Wireless light communications (LC) and visible light positioning (VLP) enable future lighting systems to provide not only illumination but also communications and positioning service. These technologies have recently attracted a great deal of attention as promising future services. In 2025, the connected lights and controllers of the lights are expected to represent a large Internet of Things (IoT) market. In particular, visible light communications (VLC) and light fidelity (LiFi) technology have large market perspectives with the prediction of the traffic’s exponential growth. Therefore, LC technologies could represent a strategic complementary solution to 5G/6G systems to overcome the scarcity of the radio frequency spectrum with a high level of security, or to support new services requiring high bit rate in sensible environments.

This Special Issue welcomes submissions which contribute to narrowing the technology gaps in wireless LC and VLP. Topics of interest include, but are not limited to:

  • Coding/modulation/multiple-access schemes for light communications (LC) including the spectrum from infrared to ultraviolet;
  • Transmitter and receiver designs for LC systems;
  • LC solutions in 5G/6G networks;
  • Optical camera communication (OCC) technologies and solutions;
  • Novel visible light positioning (VLP) systems;
  • High-performance LC/VLP applications;
  • Internet of Things (IoT) solutions using LC/VLP;
  • Virtual reality, augmented reality or extend reality (VR/AR/XR) applications using LC/VLP;
  • Applications of machine learning or artificial intelligence in LC/VLP systems;
  • Security in LC/VLP systems.

Visible Light Communication (VLC) systems are favoured for numerous applications due to their extensive bandwidth and resilience to electromagnetic interference. This study delineates various constructions of Optical Orthogonal Frequency Division Multiplexing (O-OFDM) approaches employed in VLC systems. Various factors are elaborated within this context to ascertain a more effective O-OFDM approach, including constellation size, data arrangement and spectral efficiency, power efficiency, computational complexity, bit error rate (BER), and peak-to-average power ratio (PAPR). This paper seeks to assess these approaches’ BER and PAPR performance across varying modulation orders. Regrettably, in VLC systems based on OFDM methodology, the superposition of multiple subcarriers results in a high PAPR. Therefore, this study aims to diminish the PAPR in VLC systems, enhancing system performance. We propose a non-distorting PAPR reduction technique, namely the Vandermonde-Like Matrix (VLM) precoding technique. The suggested technique is implemented across various O-OFDM approaches, including DCO-OFDM, ADO-OFDM, ACO-OFDM, FLIP-OFDM, ASCO-OFDM, and LACO-OFDM. Notably, this method does not affect the system’s data rate because it does not require the mandatory transmission of side information. Furthermore, this technique can decrease the PAPR without impacting the system’s BER performance. This study compares the proposed PAPR reduction technique against established methods documented in the literature to evaluate their efficacy and validity rigorously. Full article

Abstract
In free-space optical (FSO) communication systems, on–off keying (OOK) is a widely used modulation format. Coherent and non-coherent OOK receivers with sensitivities of −54.60 dBm and −51.25 dBm, respectively, were built with a communication rate of 1 Gbit/s and a bit error rate [...] Read more.
In free-space optical (FSO) communication systems, on–off keying (OOK) is a widely used modulation format. Coherent and non-coherent OOK receivers with sensitivities of −54.60 dBm and −51.25 dBm, respectively, were built with a communication rate of 1 Gbit/s and a bit error rate of 10−3. In an FSO communication system, the parameters must be designed to ensure a sufficient link margin. In contrast to optical fiber systems, FSO systems have ambient light (AL) noise such as sunlight. The efficiency of sunlight coupling in the single-mode fiber (SMF) of the receivers was calculated in this study. For a signal light with AL, the change in the main components of noise and the sensitivity deterioration were theoretically analyzed and experimentally verified in conditions of coherent reception and non-coherent reception with a preamplifier. For coherent reception, the theoretical sensitivity deterioration results are consistent with the experimental results which indicate that coherent reception exhibits better anti-AL noise performance than non-coherent reception when the power spectral density of the AL is the same. Coherent and non-coherent receivers coupled with SMF can work in direct sunlight. When the receiver lens diameter is greater than 4.88 × 10−4 m, the anti-AL noise performance of the receiver can be improved by increasing the receiver lens diameter. Full article
