人们对移动通信服务的需求正在迅速增长。在人口稠密的地区，为了增加蜂窝系统的容量，细胞分裂是不可避免的。细胞分裂使细胞系统具有不同大小的细胞。在小区规划中，有必要对混合小区大小的码分多址（CDMA）小区系统的反向链路容量进行分析。在本文中，我们提出了一种计算混合小区大小的CDMA蜂窝系统反向链路容量的方法。以一个宏单元分解为三个微单元为例，计算了这三个微单元与相邻宏单元的反向连接容量。结果表明，随着微单元半径的减小，微单元的反向链接容量增大，而邻近的宏单元的反向链接容量减小。
The demands for mobile communication services are growing rapidly. In heavily populated areas, cell splits are unavoidable to increase the capacity of the cellular system. Cell splitting makes a cellular system have mixed cell sizes. For cell planning, it is necessary to analyze the reverse link capacity of a code-division multiple-access (CDMA) cellular system with mixed cell sizes. In this paper, we propose a method to calculate the reverse link capacity of a CDMA cellular system with mixed cell sizes. When a macro cell is split into three micro cells, as an example, we calculate the reverse link capacities for the three micro cells and the neighboring macro cells. The results show that as the radius of a micro cell decreases, the reverse link capacity of the micro cell increases, while those of the neighboring macro cells decrease.
