Abstract :
An analytical formulation of the outage probability in terms of bit error rate specification for variable bit rate (VBR) multiclass services in the uplink of a multirate DS-CDMA-based cellular system is presented. The analytical framework is formulated for the general case in which different traffic classes have different spreading gains and within a class the users can have different spreading gains. Each user has multiple spreading codes with different data rates. The analytical work leads to the determination of the capacity region of a multirate DS-CDMA system with VBR traffic. Numerical results of the capacity region corresponding to typical parameter values are also presented.
