主要研究了Shadowing模型的2个重要参数,路径损耗指数n和误差项ε,通过实际测得场强分布,分段计算n和ε,最后将分段的Shadowing模型组合为符合实际环境的场强分布模型,为ZigBee无线定位提供很好的数学模型。
The two important parameters of Shadowing model, the path loss index n and the error term ε, are mainly studied. The field strength distribution is actually measured, and n and ε are calculated in stages. Finally, the segmented Shadowing models are combined into a field strength Distribution model, provide a good mathematical model for ZigBee wireless location.
