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.
