Noise Models in Optical Wireless Communication Systems

Optical wireless communication has received widespread attention as a high-speed, high-bandwidth communication technology. However, noise is an important limiting factor in system performance and has a critical impact on optical wireless communication systems. This chapter reviews the research progress of noise modeling in optical wireless communication systems, summarizes the research results of Ke’s model, the turbulence-noise model, thermal-noise model, background optical-noise model, etc., and further analyzes the performance of systems under the influence of turbulence. Finally, the shortcomings of current research are highlighted, and future development directions are discussed.
