Space-Time Characterization of the Mobile Radio Channel: an Implementation of the Frequency Sounding Technique

This work presents the results of an estimation of the mobile radio channel space-time dispersion in 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 array was built and calibrated, and a processing algorithm of the measured signal was tested. The chosen antennas 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 are presented and discussed.
