Abstract
A newly two-dimensional hybrid code based on Zero Cross Correlation (ZCC) and Multi Diagonal (MD) codes (2D ZCC/MD) has been proposed for incoherent spectral/ spatial OCDMA system in this paper in order to supress MAI and mitigate PIIN. The 2D ZCC/MD keep the zero cross correlation property since the both of Zero Cross Correlation (ZCC) and Multi Diagonal (MD) codes have zero cross correlation property. Using the direct detection technique the proposed code is analysed where the performance of 2D ZCC/MD code is compared with existing 2D FCC/MDW and 2D DPDC. The analytical results prove that at low BER and high data 2D ZCC/MD can support more simultaneous user.
