Channel impulse response estimation using vector network analyzer

Abstract

This paper describes the results of frequency-domain indoor radio channel characterization using vector network analyzer in the 1.7–1.9 GHz frequency band. Channel impulse response estimate was obtained via inverse Fourier transform through repeated measurements of its transfer function. Statistical parameters of radio propagation, namely the channel's power delay profile and cumulative distributions of root mean square delay spread, mean excess delay and coherence bandwidth were evaluated and comparisons with results in literature were drawn.
