Statistical Analysis of Radio Propagation Channel in Ruins Environment

الملخص EN

The cellphone based localization system for search and rescue in complex high density ruins has attracted a great interest in recent years, where the radio channel characteristics are critical for design and development of such a system.

This paper presents a spatial smoothing estimation via rotational invariance technique (SS-ESPRIT) for radio channel characterization of high density ruins.

The radio propagations at three typical mobile communication bands (0.9, 1.8, and 2 GHz) are investigated in two different scenarios.

Channel parameters, such as arrival time, delays, and complex amplitudes, are statistically analyzed.

Furthermore, a channel simulator is built based on these statistics.

By comparison analysis of average excess delay and delay spread, the validation results show a good agreement between the measurements and channel modeling results.
