“…However, the bit error rate in DPPM is higher than that in PPM [15]. The main disadvantage of this scheme is that the pulse width is very short, and the high order M-element PPM modulation VLC can improve the power and bandwidth efficiency [16]. PPM modulation index can improve the power of the system from 1 dB to 2.5 dB by reducing the average bit error rate (BER) [16].…”

“…The main disadvantage of this scheme is that the pulse width is very short, and the high order M-element PPM modulation VLC can improve the power and bandwidth efficiency [16]. PPM modulation index can improve the power of the system from 1 dB to 2.5 dB by reducing the average bit error rate (BER) [16]. OPPM signal modulation schemes offer key advantages over other existing PPM schemes, such as greater sensitivity and smaller bandwidth expansion [17].…”

“…In Ref. [16], this paper uses avalanche photodiode (APD) and the positive intrinsic negative (PIN) receivers, respectively, and considers a single input multi output system with strong gas turbulence defined by M-ary PPM modulation and gamma-gamma distribution. Then a comprehensive comparative evaluation of the two situations is carried out.…”

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.
