Performance analysis of a multimedia CDMA system using dynamic rate control

Abstract

In this paper, we propose an effective access control scheme in an voice/video/data integrated CDMA system. The proposed scheme schedules the transmission of data traffic during low voice/video traffic density period. In addition, to guarantee the delay requirements of data traffic, the transmission rate control of video traffic is triggered when the access delay of data traffic exceeds delay requirements. Numerical results show that outage probability is decreased by allowing the delay of data traffic and decreasing the transmission rates of video traffic. © IFIP International Federation for Information Processing 2005.
