Encoder-decoder design for SAC-OCDMA using Flexible Cross Correlation (FCC) code algorithms

In this paper, we present an effective encoder-decoder design utilizing Flexible Cross Correlation (FCC) code for Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) systems. The FCC code has advantages, such as flexibility cross-correlation property for any given number of users and weights, as well as effectively reduces the impacts of Multiple-Access Interference (MAI). The proposed FCC SAC-OCDMA encoder-decoder had shown superior performance indicated FCC SAC-OCDMA encoder-decoder offers 100%,287% and 331% much larger number of active users compared to MDW K=60, MFH K=31 and Hadamard K=29, respectively.
