Ultra-wideband (UWB) channel modeling relies on characterizing multipath propagation environments through statistical impulse responses and power delay profiles to enable accurate ranging and high-data-rate communication in the 3.1–10.6 GHz spectrum. The theoretical framework distinguishes between time-domain pulse sounding, which directly resolves excess delays via deconvolution, and frequency-domain vector network analyzer measurements that derive channel transfer functions ($H(\omega)$) through S-parameters to achieve equivalent characterization post-inverse Fourier transform. These models define critical metrics such as RMS delay spread, coherence bandwidth, and path loss exponents to distinguish large-scale variations (path loss), small-scale fading effects, and the specific constraints imposed by FCC fractional bandwidth regulations on system design.
