摘　　要：由于移动通信系统性能受到无线信道的制约,影响无线信道的主要因素是无线传播的地理环境,移动通信中将地形特征划分为市区、郊区和乡村三大类型。文中根据对某城市郊环境下移动通信基站信号的实地测量,运用线性回归法对Okumura-Hata预测模型进行了校正,并通过与实测数据的仿真对比,证实其预测准确度得到了明显提高。Since the mobile communicative system is restricted by the wireless signal path, while the main factor that affects the wireless signal path is the geographical conditions of the wireless signal propagation. The geographical feature of mobile communication falls into three types: urban, suburb and countryside. This paper describes the adjustment of Okumura-Hata prediction model by applying linear regression method based on the on-the-spot tests of mobile communication base stations in the suburb of a city, ...
