摘　　要：利用自动小区规划(ACP)进行深度RF优化是近年来优化工作的一个研究热点。从ACP的理论基础和一般流程等方面深入剖析影响ACP输出优化方案准确性的主要因素。这些因素包括路测(DT)数据采集方法、区域模型的划分和待优化参数初始值及变化范围的设置。用网优实际案例验证我们分析的结果,为下一步优化实践工作提供了方向。The study of automatic cell planning is one of hot-spots in the field of RF optimization in mobile communications. In this paper, a review on the theoretical basis and workflow of ACP algorithm is presented and analyzed thoroughly. The factors affecting the accuracy of the output schemes using ACP algorithm are emphasized. These factors, in-cluding methods of gathering DT data, the separa-tion of objective area, and the settings of initializa- tion and range of various parameters in the algo-rithms, are analyzed in practical CDMA optimization considerations. The modified ACP algorithm is vali-dated by the optimization results.
