An analytical formulation of the outage probability in terms of bit error rate specification for video services in the uplink of a dynamic complete partitioning (DCP) round-robin carrier-hopping multirate Multi-Carrier (MC) DS-CDMA cellular system is presented. The video model used in this paper accounts for scene changes. In the model, each video source is modeled by a two dimensional Markov chain. The analytical framework is formulated for the general case in which different traffic classes have different spreading gains in each of the subcarriers. The analytical work leads to the determination of the capacity region of a dynamic complete partitioning round-robin carrier-hopping multirate MC-DS-CDMA system for video traffic. Numerical results show that the system capacity with DCP can be larger than that with complete sharing (CS) of the subcarriers.
