2.35 GHz Near Ground Wideband Channel Measurement and Characterization

摘要

The increasing interest that has been drawn to wireless sensor network technology is therefore required measurement and analysis of wideband mobile channel with near ground antennas. Using slippage correlation algorithm, a typical suburban environment was analyzed to compare the system performance in 2.33-2.37 GHz, with antenna elevation and sensor's velocity as only variables. Large and small-scale characteristics are both investigated. Results such as channel impulse response, power delay profile, paths number, delay spread, Doppler spectrum, path loss exponent and shadowing parameter are extracted, evaluated and reported. The relationship between channel attenuation and antenna elevation, as well as the small-scale channel behaviors with different antenna heights are concluded.
