Abstract :
In this paper, the capacity of an orthogonal variable spreading factor code division multiple access (OVSF-CDMA) system supporting convergent variable rate video and data services is studied. An analytical approach for evaluating the system outage probability based on interference analysis is introduced. An optimization model to achieve maximum video and data throughput with QoS assurance and satisfactory outage probability is proposed. Numerical results demonstrate the effectiveness of the proposed approaches.
