Abstract: An optical code-division multiple access system (OCDMA) for multi-user visible light communications is presented, which interfaces with the Ethernet network. The OCDMA scheme is based on the optical codes known as random optical codes, which do not present an optimal performance but are characterised by their ease of implementation. To combat the relative poor correlation properties of this kind of code, a synchronism mechanism has been proposed and evaluated. The results obtained with the final developed prototype demonstrate the suitability of the proposed scheme for multi-user communications in a visible light environment.
