摘要
首先考虑信号在空间的链路损耗,结合中继器最低保护场强、功率及系统余量等参数的合理分析与确定,采用Egli模型得出中继器覆盖半径表达式;其次在中继器分布位置上,将蜂窝通信系统中的中心激励模型进行改进得到中心—顶点激励模型。该模型能将面积覆盖率提高4%,用户覆盖率提高22%。为通信系统中的中继器分布提供了较好的优化方案。
First considering the signal in space link loss, in combination with lowest relay protection field intensity, power and the reasonable analysis and determination of parameters such as system allowance, a repeater Egli model was adopted to cover radius expression was drew. Secondly on the repeater distribution location, center incentive model of cellular communication system was improved to the center-vertex incentive model. The model area of coverage can be increased by 4%, the user coverage increased by 22%. The repeater distribution in communication system provides a good optimization.
