中文摘要：
蜂窝系统功率控制算法，主要集中于固定信道情形，并且大多数算法都需要两个或多个比特功率控制命令．考虑信道增益是时变的蜂窝系统功率控制问题，提出了一个新的二进制反馈功率控制算法，此算法仅需要一个比特功率控制命令．在一定假设条件下，证明了每一用户的信干比收敛于一个由信干比的目标值与功率控制步长所决定的特定范围之内．仿真结果表明提出的算法是可行的，可以应用于实际的移动通信系统．
英文摘要：
A new distributed binary feedback power control algorithm for time-varying cellular systems is presented. A class of power control problems is considered where the system link gains are assumed to be time varying, and only one bit is sent back to each transmitter. It is proved that the received SIR for each user falls within a certain specific range determined by an SIR target and a power control step-size. A simulation result is given, showing the performance of the proposed power control algorithm to be adopted in practical mobile communication systems.
