Embodiment Construction

[0042] During the research process, the applicant discovered the following features of the visible light communication (taking LED as an example) system:

[0043] 1. The performance of the LED system can be significantly improved by reducing the temperature of the LED system.

[0044] Taking the calibration temperature of the LED system as 105°C, 90°C, and 75°C as an example, for the LED system, the temperature directly depends on the power. from figure 1 The simulation results shown show that for a curve with a temperature of 105°C, the allowable AC components (for communication) and DC components (for lighting) are the smallest, and when the limit temperature is 90°C, the allowable signal components and lighting components are Significant improvement, further reducing the calibration temperature, when the temperature is 75 ℃, the allowable DC component and signal component are the largest, obviously, the performance of the LED system can be significantly improved by reducin...

Abstract

The present application discloses a performance optimization method, device, equipment, and computer-readable storage medium of a visible light communication system, which acquires the bias current value and signal component value of the visible light communication system, and determines the light emission based on the bias current value and signal component value. The temperature of the device, using the temperature as a constraint condition, determines that the performance parameters of the visible light communication system meet the optimal bias current value under the preset conditions, and the performance parameters include illumination flux and AC flux. The bias current value of the visible light communication system is adjusted to an optimal bias current value, and / or, the signal component value of the visible light communication system is adjusted to a value corresponding to the AC flux. It can be seen that with the temperature as a constraint, the VLC system can be optimized from the perspective of the bias current value and the AC component, thereby improving the performance of the VLC system.

Description

technical field [0001] The present application relates to the field of visible light communication, and in particular, to a method, apparatus, device, and computer-readable storage medium for optimizing the performance of visible light communication. Background technique [0002] In recent years, the demand for high-speed data has forced new iterations of RF technology. RF technology will face many challenges such as bandwidth disputes, security and electromagnetic pollution. As an alternative to radio frequency technology, visible light communication technology has rich spectrum resources, endogenous safety, lighting, and no electromagnetic pollution. There is potential application value for communication using light as the medium. [0003] At this stage, visible light communication systems are mostly built around idealized models, that is, linearization of the modulation interval is ideally assumed. SUMMARY OF THE INVENTION [0004] In the process of research, the app...
