2D OCDMA System for Service Differentiation

Abstract

The incoherent Optical Code Division Multiple Access (OCDMA) is studied as a potential access technique for multimedia applications. In this paper, we propose to provide service differentiation with 2D codes based on Optical Orthogonal Code (OOC) namely: Multi-Wavelength Optical Orthogonal Code (MWOOC). The Quality of Service (QoS) differentiation is realized by partitioning a 2D code set into matrices with different weights. We develop the theoretical error probability expression of such system with a Conventional Correlation Receiver (CCR), and evaluate the performance in the case of three services differentiation.
