A multi-access interference avoidance scheme for an optical fibre-based CDMA LAN using optical orthogonal codes

A technique to transmit data with zero multi-access interference (MAI)-induced errors is presented. Using this method, more users are able to share the channel simultaneously by utilising a lower code weight with the same code length, compared with a conventional optical CDMA system using OOCs. As a result, the throughput and the bit error rate of the network is improved significantly.
