Adaptive Pre-Distortion Compensation for LED Nonlinear Distortion in VLC-OFDM Systems Using Frequency Symbol Spreading

This paper proposes an adaptive pre-distortion method for mitigating LED nonlinear distortion in Visible Light Communication (VLC)-OFDM systems. The inherent nonlinear characteristics of LEDs disrupt the orthogonality among OFDM subcarriers, causing signal distortion and performance degradation. To...
