摘要：
In the literature, a number of fuzzy-based power control schemes have been proposed for systems with a single service. However, emerging CDMA cellular systems are expected to include multimedia services. In such systems, different services have different quality of service (QoS) requirements, such as minimum transmission rates and tolerable delays. This paper introduces a novel adaptive fuzzy-based power control that is associated with a transmission rate management scheme to support multimedia services in CDMA cellular systems. Simulation results show that the new scheme outperforms the original selective power control (SPC) method in several performance measurements, such as outage probability, average transmission rate, probability of unsuccessful transmission, and probability of changes in transmission rates.
