In the future wideband CDMA cellular systems, services with different data rates, Quality of Service requirements, and power constraints will coexist in a cell. Multiband CDMA may be used to accommodate these heterogeneous service requirements by overlaying the subbands containing different services within the same spectrum band. In this paper we will derive the capacity of multiband CDMA systems in terms of the number of users in each service class, and the corresponding bandwidth utilization. Both reverse and forward links are analyzed. The effects of imperfect power control, other cell interference, and soft handoff are considered. The performance results are compared with the single-band system where all services share the entire system bandwidth.
