Abstract
Direct Sequence- Spread Spectrum Multiple Access (DS-CDMA) cellular networks are being designed to carry integrated voice and data traffic. Data applications require traffic rates and grades of service which differ from voice users (operating at a basic rate). In a DS-CDMA system with such a heterogeneous traffic mix, the reverse link capacity is difficult to determine. Besides, the handsets of voice users and High Speed Data(HSD) users typically have different power limitations. This has serious coverage and capacity implications. In this paper, an interference-based analysis of the reverse link is used to quantify the capacity of a single DS-CDMA carrier (loaded with voice and HSD applications). The analysis also illustrates the trade-offs of coverage and capacity required to accomodate HSD users with severe power limitations. Further, it is shown that the FER tolerance and service availability for differnt HSD applications can be traded off for enhanced capacity.
