Summary:
One of the weaknesses of the Visible Light Communication (VLC) system is its susceptibility towards noise interference which comes from indoor/artificial intelligence lamp such as modern fluorescent and incandescent lamp. Besides that, it is also susceptible to ambient light of sunlight, flashlight, LED lamp, or handphone screen light as DC interferences. In this paper, we use a low-cost analog filter to reduce static interference noise from incandescent and fluorescent light. To reduce ambient light, we use manually configurable analog DC-offset adjuster. According to the experiment result, the design is able to perform well in reducing these noise sources.
