Abstract

In this paper, we propose a new code design with one cross correlation for the Optical Code Division Multiple Access (OCDMA) system. The performance of the system with the proposed Modified FCC code is analyzed by taking into account the effect of shot noise, PIIN and thermal noise sources. From the numerical results, it is found that the Modified Flexible Cross Correlation code (MFCC) provides the best performance, in terms of the signal to noise ratio (SNR) and the bit error rate (BER), compared to MDW (Modified Double-Weight) and RD (Random diagonal) codes. Moreover, the simplicity in code construction and the flexibility in cross correlation control have made this code a compelling candidate for future Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) applications.
