摘　　要：移动通信系统要求高效复用无线信道资源。实际使用的各种复用方法都引入了某种形式的干扰，干扰的功率与发送功率成一定的比例关系。发送功率控制是平衡接收信号和干扰的关键技术，反过来这种技术也促进了无线信道资源的更高效利用。首先介绍了蜂窝移动通信系统中发送功率控制的基本理论，着重介绍了WCDMA系统中使用的快速分布式异步发送功率控制，并对功率控制技术的发展进行了展望。Economical and competitive mobile wireless services require efficient sharing of channel resources． All sharing methods in practice introduce interference of one sort or another which are proportional to the transmitter powers． Therefore transmitting power control is a key technique to better balance between the received signal and the interference which in turn enables more efficient channel resources sharing． This paper introduces the general transmittering power control technology applied in cellular mobile communications systems particularly the fast distributed asynchronous transmitting power control technique applied in WCDMA systems and foresees the future of this technology．

关 键 词：蜂窝移动通信 VCDMA 发送功率控制
