Downlink Power Algorithm Of GSM Network

Mobile communications is the communication which both or at least one mobile communication in the exchange of information.In 20th it came into ues in the military and some other special areas,and in 40th it was gradually extended to the civilian;In recently decades it is the real time of the rapid development of mobile communications,and because of its many advantages,the prospects are bright.Mobile communication has experienced from analog to digital communication development process.At present,the more mature digital mobile communications standard are pan-European GSM.Whether it's advanced 3G or the sustainable development of GSM,operators are concerned with investment and profit,in order to recover the investment as soon as possible,wireless network performance is very critical not only to increase network capacity and capability,but also to improve the end user experience the QoS.Therefore,efficient radio resource management algorithms can often be the case without a lot of investment to effectively improve the network performance,including switching algorithm,channel assignment algorithm,power control algorithm.This paper studies the power control algorithm is studied,with the major manufacturers of equipment have to use power control algorithm based on the quality of research,analysis,simulation,on the algorithm involves the step of filtering and power control is proposed to optimize the calculation process;Also by the power control algorithm based on the quality of single-step calculation for the two-step optimization approach,improve the algorithm's ability against fast fading and noise.But with the increased percentage of the mass distribution,power consumption also increased,mainly due to two-coefficient filter of the "fast rise slow down" nature of the decision,which requires power control during the process of power in the slower Its purpose is to reduce the maximum power reduction caused by fluctuations in call quality.
