Abstract
In this paper we investigate the family of prime codes 1D, 2D and 3D code for Optical CDMA communication system. Optical CDMA network works on the concept of assigning minimal interfering code sequence to each user that will intelligently route the traffic within the network. The 1D and 2D codes are compared with the proposed 3D codes based on prime sequence algorithm. The mathematically modeling of the codes is explained in detail. The orthogonality among codes is evaluated in terms of auto and cross correlation function on MATLAB. It is seen that the correlation property of the proposed 3D code is matched closely with the 1D code and better then the 2D Code. The cardinality of 3D code is better than the 1D code and almost comparable to the 2D code. The significance of introducing the dimension is explained in terms of BER versus number of user for 1D and 2D codes.
