A frequency‐domain approach for propagation measurements and characterization of indoor ultra‐wideband (UWB) channels is presented. The approach is based on measurement of the magnitude using a scalar network analyzer and retrieving the phase from the magnitude data using a Hilbert transform relationship. Extensive propagation data are collected in a frequency range of 1 to 12 GHz in two buildings on the Virginia Tech campus. Using the measured data, channel‐characterization results are obtained and compared to those based on time‐domain measurements. The statistical results for small‐scale fading, the path‐loss exponent, and signal quality are presented. The frequency‐domain results are generally in good agreement with the time‐domain results, and also reaffirm the immunity of UWB propagation to small‐scale fading. © 2004 Wiley Periodicals, Inc.
