摘要

首先结合阿拉尔市地形和建筑特点提出了一个改进的路径损耗传播模型；改进的模型中提出了沙尘因子的概念，考虑了沙尘暴对无线信号的影响；通过在沙尘天气对WCDMA基站天线发送信号的强度进行测量，并与无沙尘时测量的信号强度进行比较，使用MATLAB软件进行数据拟合得到沙尘因子，数据显示沙尘因子不仅与能见度有关，与距离基站的距离也存在一定的关系。最后针对模型进行优化前后的仿真比较，结果表明，优化后的模型更接近实际传播环境，沙尘因子的引入对移动通信传输系统的设计和布网有很大的指导意义。

Abstract

A modified path-loss model for the Alar terrain by taking the effect of dust and sand storm into account was proposed. A dust factor was introduced into the model by curve fitting operation from measured strength of the received signal from a WCDMA base station. The model verification was fulfilled by comparing with the measurement data in the scenario of no dust and performed via MATLAB. Finally，the simulation and comparison were given before and after optimization，which show that the optimized model is much closer to the practical communication channe1. The introduction of dust factor has a great guiding significance to the design and network layout of transmission system for mobile communications network.
