Relationship between delay spread and coherence bandwidth for UWB transmission

In this paper we present the results of an ultra wideband (UWB) measurement campaign carried out in an indoor environment. The UWB channel parameters were evaluated from the measured data. Specially, temporal dispersions of the multipath channel were calculated and the relationship among these parameters was studied. The sounding technique was based on the classical frequency domain over a bandwidth of 850 MHz. The temporal dispersions in the mobile radio were assessed in terms of the delay spread and coherence bandwidth.
