Design and performance analysis of eight user Spectral Phase Encoding O-CDMA time domain system at different bit rate for MANET

In optical code division multiple access (OCDMA) system, many users share the same transmission medium by assigning unique pseudo-random optical code (OC) to each user. OCDMA is attractive for next generation broadband access networks due to its features of allowing fully asynchronous transmission with low latency access, soft capacity on demand, protocol transparency, simplified network management as well as increased flexibility of QoS Hence, In this paper the performance of Spectral Phase Encoding O-CDMA System in time domain system is compared at Different bit rate from 1Gb/s to 6Gb/s for Metropolitan area Network Results indicate significant improvement in term Beat Error Rate (BER) and very high quality factor in the form of Quality of Service (QoS).SPE O-CDMA supports eight user at 4Gb/s bit rate and 6Gb/s bit rate for four users. In our analysis, we have used Pseudo Orthogonal (PSO) codes and specific phase shift codes. The simulations are carried out using OptSim (RSOFT).
