Wideband Propagation Channel Parameters Measurement Inside an University Building

Abstract

Contemporary communications are predominantly wireless. Wireless systems propagation parameters are greatly influenced by multipath fading, even more so in an "indoor" environment. Theoretical parameters commonly used for describing multipath are coherence bandwidth and multipath delay spread. The goal of this paper is presentation of results of impulse response measurements in 2.4-GHz frequency band, conducted inside FESB building, using vector analyzer method. From the obtained channel impulse response delay spread was calculated, and the estimate of coherence bandwidth was made. Measurements were divided in four sets, each showing fair correlation of coherence bandwidth and delay spread results
