Performance analysis of video services in the uplink of a round-robin carrier-hopping multirate multi-carrier DS-CDMA system

Abstract

An analytical formulation of the outage probability in terms of bit error rate specification for video services in the uplink of a 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 the uplink in a round-robin carrier-hopping multirate MC-DS-CDMA system for video traffic that accounts for slow and fast motions. Numerical results of the capacity region corresponding to typical parameter values are also presented.
