Analytical formulations of the outage probability in terms of bit error rate specification using Chernoff bound and central limit Gaussian approximation for variable bit rate (VBR) multiclass services in the downlink of a round-robin carrier-hopping multirate multicarrier (MC) DS-CDMA cellular system is presented The analytical framework is formulated for the general case in which different traffic classes have different data rates in each of the subcarriers. The analytical work leads to the determination of the capacity region of the downlink in a round-robin carrier-hopping multirate MC-DS-CDMA system for VBR traffic. Numerical results of the capacity region corresponding to typical parameter values are also presented.
