Influence of Vegetation on the Outdoor-to-Indoor Mobile Radio Propagation in 700 MHz Band

Abstract Starting from outdoor transmission, crossing vegetation, the wideband and narrowband characterization of the indoor mobile radio channel in the 700 MHz band is obtained from experiments carried out in the indoor environment of the Engineering building at Fluminense Federal University, and from the processed data, respectively, the power-delay profiles obtained permitted to calculate the time dispersion parameters and the envelope of the signal permitted to adjust probability density functions to the signal variability, concluding about the influence of vegetation on those characteristics.摘要：本研究以穿过植被的室外传输链路为初始场景，分别通过在弗鲁米嫩塞联邦大学（Fluminense Federal University）工程楼室内环境开展的实验，以及对实验数据的后处理，获取了700 MHz频段室内移动无线信道的宽带与窄带特性表征。基于处理后的数据，由所得功率时延谱可计算得到时间色散参数；通过分析信号包络，可将概率密度函数拟合至信号的起伏特性，最终总结了植被对上述信道特性的影响。
