中文说明：
把地理区域分成一个个小区，蜂窝系统在该区域内提供无线覆盖。把可用的频谱分成很多信道，每个小区分配一组信道。使用频分双工（FDD）。在小区间进行频率利用，N个小区构成一个簇，簇间进行频率复用。定义了传播特性（信道参数）以及同频小区的位置。信道的参数包括：小区半径，路径损耗指数，以分贝为单位的对数正态阴影的标准差，基站发射功率级，移动台发射功率级，每个小区的扇区数，扇区化天线的正反向比，要仿真的瞬时位置的组数，同频干扰阈值。
English Description：
The geographical area is divided into cells, and the cellular system provides wireless coverage in the area. The available spectrum is divided into many channels, and each cell is allocated a group of channels. Use frequency division duplex (FDD). Frequency utilization is carried out among cells, n cells form a cluster, and frequency multiplexing is carried out among clusters. The propagation characteristics (channel parameters) and the location of the same frequency cell are defined. The channel parameters include: cell radius, path loss index, standard deviation of lognormal shadow in decibels, base station transmission power level, mobile station transmission power level, number of sectors in each cell, forward and reverse ratio of sectorized antenna, number of groups of instantaneous positions to be simulated, and co frequency interference threshold
