分布式卫星系统的上/下行功率联合控制
Uplink and Downlink Joint Power Control in Distributed Satellite System
摘要
Abstract
In order to reasonably control the power of thedistributed satellite system ( DSS ) to improve its system capacity,the joint power control problem of the system is studied. Through analysis of the character-istics of DSS and the difficulty of power control problem,the power control model and the architecture of power control approach are constructed. A joint power control approach based on preset, prediction and multi-stage adjustment is proposed. Finally the effectiveness of the approach is verified with the perform-ance comparison between the approach and traditional scheme based on prediction and single-stage adjust-ment. The proposed approach can better meet the demand of the power threshold as the up and downlink in different rainfall percentage condition. The approach can more accurately track the rain attenuation in both curves measured in Guangzhou and Changchun. When the services and the communication zone are changed,the approach can quickly switch the network and keep the dynamic tracking. The approach meets the application requirements of accuracy and timeliness for the power control problem of DSS.关键词
