In this paper, we propose a new method for creating more distinguishable QoS levels in OCDMA networks. The key idea behind the proposed scheme is to adaptively controlthe transmit power level in each chip based on OCDMA channel state. The structure of the transmitter and receiver are proposed.We provide performance analysis of the recommended scheme and show that it can reduce the system BER and provide betterQoS differentiation in a multiclass network. We provide simulation results and demonstrate that they have a good match with the results obtained from mathematical analysis
