Abstract

This work presents the results of an estimation of the mobile radio channel space-time dispersion at 1.8 GHz, through the use of the frequency sounding technique. Some changes in the classical technique were implemented: a set of antennas known as an array was built and calibrated, and a processing algorithm of the measured signal was tested. The chosen antenna array is circular with 8 elements. Measured data were taken in a small indoor environment in the campus facility. Results accomplishing for the main propagation mechanisms in the tested scenario are reported, and the technique performance is presented and discussed.
