| 摘 要： | 功率控制是CDMA通信系统的研究热点之一。传统的反向闭环功率控制方法在移动台大功率发射时，并不总能保证接收信号质量，有时反而会造成大的系统内干扰。本文对此提出了一种实用的功率控制策略，通过适当限制对信道衰落的补偿，减少了不必要的干扰，提高了系统的整体效益和功率利用率。

| Abstract: | Power control is one of the study thrusts in CDMA communication systems. With the traditional reverse close-loop power control method, the transmission with large power level at a mobile station may not always ensure the sufficient improvement of signal quality and sometimes it generates severe interferences in the system, especially when the system is congested. So, a practical policy of reverse close-loop power control is proposed. By restricting the compensation of channel fading properly, the unnecessary interferences are decreased and the whole efficiency and power utilization ratio of the system are improved. |
