Adaptive Modulation Control for Visible Light Communication Systems

Visible light communication (VLC) builds on the dual use of lightening infrastructure for communication. Even though advantages VLC are well known, as emerging paradigm, some open issues still need to be addressed in order rely it a robust system. First all, external interference an extremely varying signal impacting reliability system needs analyzed. In this article, we propose where link conditions (in terms signal-to-noise-ratio (SNR)) drive modulation scheme and procedure is managed through uplink/channel, assure feedback path. The receiver charge choosing matching requirement error rate basis measured SNR after noise mitigation. feasibility its effectiveness evaluated by designing implementing complete bi-directional particular, uplink channel sending information regarding specific selected technique has been implemented whole based fine synchronization approach “track” real time most suitable scheme. Experimental results show implement adaptive able follow environmental changes noise).
