摘要：Design and analysis of a new class of code for the Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) system is presented. The proposed code is called the Flexible Cross Correlation (FCC) code. The FCC code has advantages such as the flexibility in-phase cross-correlation given any number of users and weights. These proposed codes can effectively suppress Phase Induced Intensity Noise (PIIN), has the Multiple Access Interference (MAI) cancellation property and easy in the code construction. We found that, from the theoretical analysis, FCC code had better achievement indicated that, the FCC code can accommodate 240 simultaneous users as compared to former SAC-OCDMA codes. FCC code also has low effective receive power (Psr) equal to -21 dBm at error floor 10-9. The extensively simulation results, FCC code are well up to 45 km at system performance BER 10-9 for bit rate 155 Mbps as compared to 622 Mbps only perform 10 km with exponentially increases to BER 10-2 error floor.
