“…In VLC, Light-Emitting Diodes (LEDs) serve as highly energy-efficient light sources, catering to both communication and illumination needs, while photodiodes function as receivers. Communication through LEDs is recognized as environmentally friendly and can operate under typical lighting conditions without causing radiation harm to humans [283].…”

As assisted driving technology advances and vehicle entertainment systems rapidly develop, future vehicles will become mobile cinemas, where passengers can use various multimedia applications in the car. In recent years, the progress in multimedia technology has given rise to immersive video experiences. In addition to conventional 2D videos, 360° videos are gaining popularity, and volumetric videos, which can offer users a better immersive experience, have been discussed. However, these applications place high demands on network capabilities, leading to a dependence on next-generation wireless communication technology to address network bottlenecks. Therefore, this study provides an exhaustive overview of the latest advancements in video streaming over vehicular networks. First, we introduce related work and background knowledge, and provide an overview of recent developments in vehicular networking and video types. Next, we detail various video processing technologies, including the latest released standards. Detailed explanations are provided for network strategies and wireless communication technologies that can optimize video transmission in vehicular networks, paying special attention to the relevant literature regarding the current development of 6G technology that is applied to vehicle communication. Finally, we proposed future research directions and challenges. Building upon the technologies introduced in this paper and considering diverse applications, we suggest a suitable vehicular network architecture for next-generation video transmission.

Visible light communication (VLC) has contributed new unused spectrum in addition to the traditional radio frequency communication and can play a significant role in wireless communication. The adaptation of VLC technology enhances wireless connectivity both in indoor and outdoor environments. Multiple-input multiple-output (MIMO) communication has been an efficient technique for increasing wireless communications system capacity and performance. With the advantages of MIMO techniques, VLC can achieve an additional degree of freedom. In this paper, we systematically perform a survey of the existing work based on MIMO VLC. We categorize the types of different MIMO techniques, and a brief description is given. Different problem-solving approaches are given in the subsequent sections. In addition, machine learning approaches are also discussed in sufficient detail. Finally, we identify the future study direction for MIMO-based communication in VLC.

“…In recent years, visible light communication (VLC) systems have attracted widespread attention because the existing radio frequency spectrum might not be able to meet the ever-growing requirement for high-speed wireless communication. VLC systems utilize visible light as the carrier to transmit signals and have been applied in various scenarios, including indoor environments, 1,2 underground mining operations, 3,4 and vehicle-to-vehicle communications. 5,6 Considering the information transmission in intensity modulation with direct detection (IM/DD)-based VLC systems, the transmitted signals have the constraint of non-negative and real values.…”

.A multilayered optical orthogonal frequency division multiplexing with offset quadrature amplitude modulation (LO-OFDM/OQAM) scheme is proposed for visible light communication (VLC) systems, which is inspired by the enhance optical OFDM/OQAM (EO-OFDM/OQAM) scheme. In this scheme, multiple layers of data are superimposed on the normal branch to further improve the spectral efficiency and power efficiency of the VLC systems. Specifically, the negative time-domain signals on each layer can be directly clipped as zeros without losing any information and demolishing the real-field orthogonal condition of the optical OFDM/OQAM system. Theoretical derivation is then given to prove the feasibility. Spectral efficiency, peak-to-average power ratio performance, bit error rate (BER) performance, and power efficiency of this proposed scheme are further investigated and compared with those of its counterparts. Simulation results show that the proposed LO-OFDM/OQAM scheme could achieve better BER performance in comparison with EO-OFDM/OQAM and DCO-OFDM/OQAM schemes, and at the same time, it is more power efficient. Our work would benefit the research and development of VLC systems.
