Adaptive receiver for visible light communication system

The future of visible light communication (VLC) systems relies on achieving moderate to high data rates and the ability to design a low complexity system, as these will play a major role in the next generation communication networks. In this paper, we propose, design, and evaluate the use of an adaptive receiver to mitigate the inter-symbol interference (ISI) and improve the overall VLC system performance while using a single element wide field of view (FOV) photodetector. In addition, we optimise the adaptive receiver by employing a different number of buffers to find the optimum configurations in terms of reducing the complexity and achieving the best performance. The proposed adaptive receiver is able to provide data rates of 1 Gbps with a BER of 10¯⁵ for OOK modulation in the worst case scenario.
