Phase Induced Intensity Noise Evasion in SAC-OCDMA Systems Using Flexible Cross Correlation (FCC) Code Algorithm

Abstract

Abstract: In this paper, a new class of codes called the Flexible Cross Correlation (FCC) code is presented. The FCC code is significant in Spectral Amplitude Coding -Optical Code Division Multiple Access (SAC-OCDMA) systems since these codes effectively evasion the effects of Phase Induced Intensity Noise (PIIN) and also has the Multiple Access Interference (MAI) cancellation property. The FCC code can be constructed using a simple tridiagonal matrix with shortest code length for any given number of users and Hamming-weights. The proposed coding systems utilizing FCC code has been analyzed with the presence of different noises such as shot noise, PIIN noise and thermal noise, respectively. The results revealed ours proposed FCC code indicated good performance since these codes offers 183%, 325%, 347% and 466% as a contrast to former SAC-OCDMA codes such as MDW (w=4, K=60), (w=6, K=40), MFH (w=8, K=38) and Hadamard (K=30), respectively. Furthermore, an extensive simulation results shown at 10km, taking the threshold cutoff BER 10 -9 , the FCC code could support 0.9Gbps for w=10 without requiring any amplifier
