Improved BER Performance Using Novel ELM Based Demodulator for CAP-VLC System

Recent trends in the field of communication science show that most devices are built and governed by Visible Light Communication (VLC) and Light Emitting Diodes (LED). The communication process depends on source characteristics and bandwidth restriction, and effective methods of modulation and demod...
