The Open Loop Power Control in the CDMA Reverse Link

在ＣＤＭＡ移动通信系统中，功率控制是提高系统容量的关键技术之一。作者在文章中首先介绍了反向功率控制的概念。然后提出了一种优化的开环功率控制算法，利用此算法移动台发射的功率最小，从而减小了干扰电平。在开环控制中，移动台检测总的接收功率，然后利用此检测值估计传播路径损耗。

Power control is a key technique for improving the capacity of CDMA mobile communication systems. This paper begins with an introduction to the concept of reverse power control, and then proposes an optimized algorithm for the open loop power control which can reduce the transmission power of the mobile and the level of interference to a minimum. In the open loop control, the mobile measures all the received power and then uses the measurements to estimate the transimission loss. The transmission power of the mobile is equated with a constant minus the measured received power.
