一种多步长功率控制算法

A multistep power control algorithm

提出了一种可以应用于CDMA系统的多步长功率控制算法,本算法根据接收端的实测信干比与目标信干比的差值,从4个步长中选取一个,对发射端的发射功率进行调整。由于步长是有限个固定值,因此该算法易于实现。通过仿真证明,该算法性能优于可实际应用的FS算法,接近于性能理想而难于实现的FMA算法。

This paper proposed a new algorithm, which can be use in the actual CDMA system for power control. The new algorithm can change the transmit power by one of several steps by compare the test SIR with the target SIR. Because there are only several steps, the algorithm can be use in the real system. The analytical results show that the performance of the proposed algorithm is better than FS algorithm.
