Simulation and performance analysis of OCDMA systems based on 2-D W/T codes

摘要

Optical signal processing is advantageous since it can potentially be much faster than electrical signal processing and the need for photon-electron-photon conversion would be eliminated. OCDMA is one such technology to realise multiple access by coding in the optical domain. It supports multiple simultaneous transmissions in the same time slot and the same frequency. This paper analyzes the performance of OCDMA system using different types of 2-D W/T codes that serve as signature sequences for users in terms of BER.
