摘要: In this paper, the UWB channel characterization is presented considering stationary and mobility scenarios in an indoor environment based on data collected through time domain measurements. The measurement conducted along corridor using pulses with frequency range of 3.1–5.3 GHz. First, path loss model, specifically log normal shadowing used to characterize channels for large-scale. It found that exponents studied are almost same. Secondly, dispersion parameters root mean square (RMS) delay spread excess (MN-EX) applied characterizing multipath dispersion, while parameter defined as gain (MG) computed measure strength component channels. For both scenarios, it average values also similar. However, MG value case outperforms one by 2.6 dB. An extensive analysis performed understand correlation RMS MN-EX delay; transmitter (TX)-receiver (RX) separation distance. addition, interdependencies between studied. results showed correlations independencies closely depend physical structure environment. shown varies 0.06 0.84
