| Abstract: | A new closed-loop control model is proposed to make an effective ananlysis of the rate control mechanism for the reverse link in CDMA2000 1x EV-DO systems.Using discrete-time control theory,the rate control blocks for both the base station and the terminals are designed to construct the closed-loop control model.This model is used to analyze system stability and transient performance.Furthermore,the rate control block is designed by root locus design,and system stability and response time are validated by c... |
