Impact Statement:
The submitted work describes cooperative communication for OFDM based VLC systems, particularly with full duplex relaying. Full duplex relaying methodology does not require any sophisticated signaling mechanism but significantly improves the performance. It can easily be adopted and implemented by the skilled engineers. Moreover, we believe the developed realistic channel models, themselves, have potential be quick reference for the scientists and engineers in the field.
Abstract:
In this paper, we investigate cooperative visible light communication (VLC) system where an intermediate light source acts as a relay terminal. We assume that relay terminal operates in full-duplex mode. In contrast to radio frequency counterparts, full-duplex VLC terminal is relatively easier to implement due to directive propagation characteristic of light. We first model VLC relay terminal taking into account loop interference channel based on ray tracing simulations. Then, we investigate error rate performance of the relay-assisted VLC system. Our performance evaluations demonstrate the superiority of full-duplex relaying over half-duplex counterpart especially for high modulation sizes.
