摘　　要：高空平台(HAPS)通信系统是近年来正处于先期研究的新型信息系统。理论分析了非理想功率控制和多用户检测(MUD)对HAPS通信系统上行链路的影响,分析这两种技术的工作原理,探讨在WCDMA应用中结合使用两种技术的可行性和方法。The high altitude platform station （HAPS） is a new information system that has been developed at an eady stage in recent years. In this paper, the impact of both imperfect power control and multiuser detection （MUD） on the uplink of a WCDMA HAPS system is analyzed as well as the principle of their operation is introduced. The feasibility and method to unite power controlling and multiuser detection in a WCDMA system is discussed.

关 键 词：HAPS 功率控制 多用户检测
