Summary:
The present paper focuses on Stochastic Resontance (SR), which is well-known as a phenomenon that enhances the response by additive noise, and employs SR on an LED visible light communication (LED-VLC) receiver. We consider that VLC receiver with SR system can detect the transmitted signal component from the distorted optical signal due to an influence of ambient light noise. In order to quantitatively evaluate SR phenomenon of this system, we perform circuit experiments using the LED-VLC system using SR system and measures input/output characteristics of the receiver. In addition, we calculate an output power spectrum density (PSD) against the noise.
