Abstract

In this paper, we propose an extension of two dimensions (2D) code cardinality. The code, developed for optical code division multiple access (OCDMA) system is generated by: merged M-sequences for the frequency hopping (in this work we consider the optical fast frequency hopping technique: OFFH) and the hyperbolic code for the time spreading. For familiespsila codes, minimum cross-correlation constraint (lambda_c= 1) is applied to decrease the multiple access interference (MAI). Compared with the 2D code employing prime code for the time spreading, the extension will increase the cardinality to P(P - 1)² users (proposed code) instead of P² users.
