Abstract
This paper conducts a simulated experiment to compare the communication and energy transfer performance between DC-bias dimming control and PWM (Pulse Width Modulation) dimming control when employing PPM (Pulse Position Modulation) based modulation in SLIPT (Simultaneous Lightwave Information and Power Transfer) using LED and SC (Solar Cell). The performance differences and the underlying reasons for these differences are analyzed comprehensively by considering the structural differences in the modulated signals, the physical characteristics of the receiving end SC, and the channel characteristics. Additionally, when implementing FSO (Free-Space Optical) communication under conditions of significant vibration, three experimental performance evaluations were conducted, considering distance, horizontal displacement, and angular changes for alignment. Through these experiments, the paper provides insights into the changing trends of the considered factors in FSO implementation, serving as criteria for achieving the targeted performance standards
