Abstract
In visible light communication (VLC) systems, optical orthogonal frequency division multiplexing (OOFDM) is used to reduce the effects of inter-symbol interference while simultaneously achieving fast data transmission speeds and large bandwidths. Asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) is one of the most OOFDM used. ACO-OFDM with low peak-to-average power ratio performance becomes essential for practical visible light communication broadcasting systems due to non-linearity elimination. The techniques for reducing the peak-to-average power ratio for visible light communication broadcasting systems are designed, simulated, and evaluated in this work. This work provides novel mixed non-linear Companding Techniques that target remarkable peak-to-average power ratio performance with acceptable bit error rate performance for ACO-OFDM-based VLC systems. This work compares the designed techniques then nominates an optimum one that provides the optimum peak-to-average power ratio and bit error rate performance. Finally, the nominated technique will be compared to all related works of literature on ACO-OFDM-based VLC systems to ensure its novelty, validity, and effectiveness.
