Abstract
This letter addresses the fading statistics of a radio propagation channel in a ruins environment, which is of vital importance for a pedestrian localization system based on cellphone signals. The channel of ruins is investigated in eight typical rescue scenarios at two common mobile communication bands (900 MHz and 1.8 GHz). To characterize the channel, an empirical path loss model is parameterized through experiments. Based on extensive measurements, large-scale fading characteristics at different polarizations and various antenna heights are examined and analyzed. Furthermore, the properties of small-scale fading including coherence bandwidth, decorrelation distance, and distance-dependent features are studied in this work. The results reported here can be applied to simulate the ruins channel and design the rescue system.
