On The Statistical Multiplexing of Optical Code Division Multiple Access

The aim of this paper is to contribute to the understanding of teletraffic behavior in optical code division multiple access networks. It explains a model of traffic capacity and its sensitivity to various parameters. Analytical model for OCDMA with and without call admission control were analyzed. However they have some disadvantage by ignoring the stochastic variation in circuit activity. It begin with the analysis of circuit switched OCDMA where circuit carrying bursty data. The analysis is independent of the OCDMA implementation or spreading code. In it considering a voice system which employs a power control and a variable rate vocoder. An OCDMA network has been taken where each user operates and can randomly access the network without the need of synchronization with respect to other user. It is assumed the circuit activity as a random variable and a class of networks which having different class of circuit activity. This has been shown that the traffic capacity of an OCDMA network is improved when circuit activity is a random variable and a heterogeneous data network is taken.
