Guojian Chen · Wireless Communication Technology · 2007
In TD-SCDMA system,power control is one of the key technologies of radio resource management;it plays a significant role in guaranteeing the high quality communication of the system.In order to decrease the Bit Error Rate(BER) of transmission information,this paper studies an adaptive power control algorithm for uplink against the power control module of TD-SCDMA system.By the simulation in the software MATLAB,this algorithm and the step size fixed power control algorithm in the physical layer simulation platform of TD-SCDMA system are compared,and the performance characteristic of the two algorithms is analyzed.Simulation results demonstrate that the adaptive power control algorithm has better feasibility and effectiveness;it has practical effect on decreasing BER and increasing system performance.
