TD-SCDMA功率控制算法研究
首发时间:2010-12-13
摘要:本文全面分析了TD-SCDMA中的内环功率控制,并在信道条件比较差的情况下,对现有的功率控制算法提出了改进算法。在进行内环功率控制之前,先通过分析接收信号的质量来分析当前信道质量,当信道条件正常时采用已有的功率控制算法进行调整,当信道条件较差时,对该用户进行功率补偿。提高其发射功率,直到信道条件变好将重新进入内环功率控制中。这样就在一定程度上减少了信道恶化引起功率控制失调。

The Power Control Algorithm of TD-SCDMA
Abstract:This paper comprehensively analyzes the power control in the TD-SCDMA. When the channel environment is poor, this paper presents an improved algorithm on the basis of existing power control algorithms. We analyze the quality of received signal to learn the current quality of channel before the inner-loop power control, when the channel environment is good the existing power control algorithm is used, and when the channel environment is poor, user will get power compensation. Raise its transmitting power until the channel environment turns to good and returns to the inner-loop power control. And we can reduce the harm of worsening of channel on the power control.
