摘　　要：移动通信衰减模型是运营商进行网络优化部署时的一种重要技术方法。传统移动通信衰减模型多适用于2G/3G低频段,而在针对3G/4G高频段进行网络优化时仿真结果不准确。通过使用MATLAB仿真软件,结合试验数据,提出了一种适用于1500~3000 MHz频率区间的移动通信空口电磁衰减模型。实践表明,新的衰减模型提升了移动通信3G/4G频段空口衰减预测的准确性,提升了运营商网络优化部署和维修保障的工作效能。The mobile communication propagation loss model is an important technical method for mobile network optimization.Most of the traditional 2G/3G mobile communication propagation loss models are based on low frequency,the result of simulation for high frequency propagation loss of 3G/4G mobile communication is not accuracy.Based on MATLAB simulation software and experimental data,a propagation loss model of mobile communication suitable for 1500~3000MHz frequency is presented.Based on the new model,the accuracy of propagation loss for 3G/4G mobile communication and the efficiency of mobile network optimization have been improved.
