Non-linear Compensation of Multi-CAP VLC System Employing Pre-Distortion Base on Clustering of Machine Learning

We proposed and experimentally demonstrated a pre-distortion scheme based on clustering algorithm of machine learning to mitigate nonlinear impairments for VLC system. BER degraded at least 50% over 5-band CAP16 transmission with pre-distortion.
