A UWB Power Delay Profile Data Acquisition for Indoor Environments Using a Spectrum Analyser

This paper presents a measurement system for indoor characterization of UWB channels. The presented method uses a scalar network analyzer (SNA) or a spectrum analyzer (SA) with tracking generator, connected to two antennas: a receiving and a transmitting one. This setup, which obtains only the magnitude data of the frequency response, makes the method less expensive when compared with other setups presented in the literature. From the magnitude data of the frequency response, a processing algorithm obtains the phase data of the frequency response making it possible to calculate the channel power delay profile. The tests for validation of the method are detailed herein
