Abstract

CDMA2000 1xEV-DO is one high data rate system based on 3G, in which access terminals have the abilities to quickly transmitdata from one rate to another and to sup port high burst rates. So the rise-over-thermal control algorithm in reverse link should be used to ensure the stability of reverse link. It is difficult for existing reverse load control algorithm to balance reverse link throughput and rise-over-thermal control in the CDMA systems. This paper designed incremental PID reverse link load control algorithm, which turned the related parameters based on fuzzy models. This algorithm can not only decrease calculation time but also realize the balance between reverse link throughput and rise-over-thermal control.
