Design and Implementation of Adaptive Power Control in 3G System

摘要

This paper,through the analysis of the factors which impact the power control accuracy in 3G system,it analyzes and compares the traditional power control methods,and,using contrast,simulation and so on,it strikes an adaptive variable step-size closed-loop power control algorithm,which can improve the controlling accuracy and convergence rate,and increase system stability and capacity.Combined with multi-path RAKE receiver,it estimates and simulates the power and SINR of received signals.
