摘要
在对单频网多年跟踪研究的基础上,首先总结分析了单频网建设的原则,以及单频网内产生自我同频干扰的条件,针对此类单频网的同频干扰现象,首次提出了单频网优化调整的指导思想和优化原则,在此指导思想和原则下,全面深刻地分析了单频网的各种优化方法和技术手段,为单频网的规划设计提供理论指导和思想借鉴。
The construction principle of single frequency network （SFN） and condition of self-interference in SFN are firstly summarized and analyzed based on massive tracking study in this paper. Secondly, the guiding ideology and rules of optimizing the area of SFN are put forward on the self-interference in SFN. Finally, the optimization method and techniques are completely and deeply illustrated. This paper will provide theoretical guidance and reference thoughts for SFN planning and design.
