Abstract

In CDMA mobile communication systems, voice is encoded and packaged in variable length packets that are transported between the mobile station and the switching center. While the packetization provides great flexibility in resource allocation, it poses a QOS challenge on voice. We discuss link dimensioning for a typical CDMA system. We consider a communication link connecting a CDMA base-station and mobile switching center. We analyze the resulting queueing system using large deviations theory and provide results for the minimum link capacity needed to support a given number of CDMA voice sources. Our results show the potential gain that can be achieved by statistical multiplexing of voice sources and discuss the effects of the statistics of the voice process on the multiplexer performance
