宏小区无线电波传播预测模型仿真分析

无线电波传播模型主要用于计算无线电波传播路径损耗中值.针对宏小区无线电波传播需要考虑地形、环境类型以及构成环境的材料等各方面因素,研究了奥村经验模型中参数的算法和取值,用MATLAB仿真依据线性回归校正算法校正奥村经验模型.仿真结果表明,在频率一定的情况下,随着收发距离d的增加,电波传播路径损耗也增大;建筑物的密度越大,电波传播路径损耗越大.仿真结果与实际环境测试数据一致,也验证了校正的奥村经验模型的可靠性.

Simulation Analysis of Prediction Model of Radio Wave Propagation in Macro Cell

ABSTRACT Radio wave propagation model is mainly used for calculating radio wave propagation path loss in value, to predict the electromagnetic propagation in a region. The value decided by the electromagnetic propagation and transmission distance. Propagation models need to consider the type of terrain and environment, and constitutes a material, and other aspects of the environment, should be based on each of the specific geographical conditions, adjust accurately describes signal propagation characteristics of electromagnetic wave propagation model in the region. This article is based on propagation characteristics of radio waves in the community, research on Olympic village experience algorithm and value parameters in the model. Linear regression calibration algorithm based on empirical model parameter calibration, correction by MATLAB simulation model of Olympic village experience. Verify the correction of Olympic village experience in macro community radio wave propagation model in the forecasting process.
