Channel Measurement and Analysis at Emergency Frequency Band in Primeval Forest

In this paper, fixed-point channel measurements for emergency communication scene in the primeval forest were conducted at emergency communication frequency band. We estimate and model channel characteristics based on the measured data within 100 m by taking 5 m as the step fixed point in the primeval forest. The emergency frequency band is 380 MHz and the corresponding bandwidth is 20 MHz. Based on the measured data, we obtain the power delay profile (PDP) of different distance. Finally, multipath components (MPCs) and large-scale fading characteristics at different distances are analyzed which contributes to make primeval forest emergency communication more reliable.
