A 3 × 25 Mbps WDM-Ro-VLC System for Amateur Radio Applications
Radio over visible light communications (Ro-VLC) can be a pioneering technology to provide ubiquitous radio services particularly in the radio network-permitted locations. In this work, three channels, each up-converted to a 50 MHz radio signal carrying 25 Mbps data, is transmitted over a 0.5 m visible light communications link by using the cost effective on-off key (OOK) modulation format. Three red, green and blue light emitting diodes are adopted for parallel transmission. We show simulation results, carried out using OptiSystem™ software, for the bit error rates for the proposed diffuse system for both nonreturn to zero and return to zero data formats.
