“…PPM has been developed as an alternative communication technology to improve the anti-interference capability of information transmission. PPM is a good way of modulation [14]. Considering the bit error rate performance, bandwidth requirements, optical power, and optical implementation complexity, PPM modulation is a viable candidate for VLC communication.…”

This chapter includes five parts—the concept of vehicle-to-anything (V2X), introduction of visible light communication (VLC), free-space optical communication (FSO), and terahertz (THz). The first part will present the concept of V2X. V2X is the basis and fundamental technology of future smart cars, autonomous driving, and smart transportation systems. Vehicle-to-network (V2N), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-people (V2P) are included in V2X. V2X will lead to a high degree of interconnection of vehicles. The concept of VLC is presented in the second part. Intelligent reflecting surface (IRS) for nano-optics and FSO communication is introduced in the third part. At the same time, IRS keeps pace with the phase in communication links. Prospects of THz in glamorous cities are introduced in the fourth part. These new technologies will lead to trends in the future. A comparison of optical communication technology and applications in V2X is described in the fifth part.

“…OPPM signal modulation schemes offer key advantages over other existing PPM schemes, such as greater sensitivity and smaller bandwidth expansion [17]. A priority decoding OPPM error correction scheme is proposed, which can significantly improve the system's BER without affecting the system bandwidth [14].…”

“…On the other hand, there will not be a pulse broadcast for 000 PCM when the OPPM is differential. The PCM term is removed from the MSB, and it is delayed by 2 m-1 time slots when it is passed via the decoder and OPPM coder [11]. Fig.…”

Error correction codes, often known as ECC, play a significant part in the process of detecting and correcting data mistakes that occur through communication channels that are unreliable or noisy. The essential concept behind error correction through ECC is to supplement the message that is being sent by the transmitter with redundant bits, the values of which are determined by the parameters n and k. These bits can then be utilized by the receiver to identify and correct specific types of errors. ECC is utilized in a wide variety of applications, including but not limited to data storage, the Internet, and telecommunications. There are numerous variations of ECC, including linear block, convolutional, and turbo codes, among others. The results of a simulation of a linear block reed Solomon, for example, with offset pulse position modulation have been presented in this study. The simulation was carried out in very high-speed integrated circuit hardware description language (VHDL), and a field-programmable gate array was used (FPGA) It made use of a Boolean function to function to program code for an algorithm that is working. Because of its performance, time to market, cost, reliability, and long-term maintenance benefits, FPGA is an appropriate platform for implementing error correction code (ECC). As a part of this project, the technique of offset Pulse Position Modulation (Offset PPM) was invented as an outstanding solution to code the fiber-optic applications and Reed Solomon (RS) codes apply to ModelSim SE-64 10.5 software. In addition, this coding scheme has been approved by the simulation and is matched with theory, and it is expected to be implemented shortly. The study begins with a concise introduction to RS encode/decode about design and performance and then moves on to discuss the development result of simulation and hardware implementation.
