En Madrid (Spain), 22-24 septiembre 2008 In this paper, an adaptive optical codes-based system is proposed for communications over the indoor wireless optical channel when large numbers of users access to the channel simultaneously. The designed system uses a code-division multiple access scheme based on the named random optical codes (ROCs). The characteristics of this kind of optical codes are described. Several results about its performance over noisy indoor wireless optical channels are also presented. Finally, a code-division multiple access system which is able to adapt its data rate to the number of users which are accessing simultaneously the channel in each moment is described. The obtained results show as the proposed system is able to maintain a target bit error rate adapting its data throughtput when the number of users in the optical environment changes.
