Abstract

A new hybrid PPM-CDMA is proposed for the mobile indoor infrared network. The technique provides asynchronous multiple access where each user (or facility on the network) is assigned a signature code belonging to the class of optical orthogonal codes (OOC). Original results are presented indicating that there exists an optimum PPM-CDMA order that maximises the achievable bit rate at a given number of users. Performance results are presented and the optimum operating parameters are specified
