Performance analysis of modified two dimensional Golomb code

Abstract

This paper presents a novel two dimensional (2D) wavelength hopping time spreading (W/T) code based on a technique of folding of the Golomb ruler that is referred in this paper as Modified Golomb Code (2D MGC) for optical code division multiple access (OCDMA) system. The proposed 2D code possesses good auto correlation, minimum cross correlation, and high cardinality. The performance evaluation of OCDMA system based on 2D MGC W/T code is analyzed in terms of BER and received optical power. The simulation is validated through the use of the optisystem software. The optimality of the proposed 2D MGC W/T code is also checked by putting the necessary boundary conditions.
