Performance Analysis of Zero Cross-Correlation Code in Spectral Amplitude Coding-OCDMA

Optical Code Division Multiple Access (OCDMA) has bright future in communication because of its faster speed, efficiency, security and unlimited bandwidth. To reduce Multiple Access Interface (MAI) and Phase Induced Intensity Noise (PIIN) noises there are many codes in Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) with codes best property i.e., minimum cross-correlation property. But Zero Cross Correlation (ZCC) code used in SAC-OCDMA with zero cross correlation property is more scalable, flexible and enhance the system performance. This paper focusing on the study of ZCC code design with code most important zero cross-correlation property and analyse its performance. The result shows that ZCC code gives bit error rate of 2.7 × 10 -20 at distance of 20km for 5 no. of users with data rate of 155Mbps. It also shows using the ZCC code leads to simplicity in system design, cost effective, reduce the MAI and PIIN noises through the zero cross correlation property. The simulation result analysed in optisystem 7.0.
