| 摘 要： | 提出了移动通信系统中一种自适应变步长的功率控制算法。在此算法中系统根据接收到的功率控制比特格式自动调整功率控制步长,然后与固定步长功率控制进行比较,可以更好的克服信道衰落所带来的影响。由于对接收功率测量的精确程度决定了功率控制的效果,因此在功率控制机制中功率测量是十分重要的。

| Abstract: | We analyze and study a new algorithm of power control technique based on adaptive variable step size in communication systems.In this algorithm,The system automaticly adjust power control step size on receiving to power control bit scheme,and compared with fixed step size power control one.The better one overcomes influence of channel fading.Because the result of power control is determined by the accuracy of power receiving measurement,power measurement is important in power control. |
