Simulation of a 3 Gb/s SAC-OCDMA Based on Multi-Diagonal Code

In this paper we've modelled and simulated a 3Gb/s (3×1Gb/s) optical system supported spectral amplitude coding writing for the optical code-division multiple-access (SAC-OCDMA) theme. So as to cut back the result of multiple-access interference, we've utilized a replacement family of SAC-OCDMA codes known as a multi-diagonal (MD) code. The new code family supported the MD code reveals properties of zero cross-correlation code, flexibility in choosing the code parameters and support of a large no of users, combined with high rate. each the numerical and simulation results have to make clear that our optical system supported the MD code will accommodate most numbers of co-occurring users with higher rate transmission and lower bit error rates, compared to the previous SAC-OCDMA codes.
