Wideband frequency selective fading evaluation in indoor environments

This paper presents the evaluation of frequency selective fading from the results of measurements taken with a 300 MHz wideband signal. A description of the sounder used in the measurements is given, as well as its performance in terms of frequency and delay spread resolution. The bandwidth is divided in segments to evaluate the frequency selective fading with segments as small as 1.25 MHz. Plots are provided for a number of locations in 4 different indoor environments. It is shown how the signal level in different consecutive segments changes and it is also shown that the overall change of the signal level due to frequency selective fading, in a specific environment, is concentrated within specific signal levels.
