The knowledge of the propagation channel properties is an important issue for a successfuldesign of ultrawideband (UWB) communication systems enabling high data rates in short-rangeapplications. From an indoor measurement campaign carried out in a typical laboratory environment,this paper analyzes the path loss and time-dispersion properties of the UWB channel. Values of thepath loss exponent are derived for the direct path and for a Rake receiver structure, examiningthe maximum multipath diversity gain when an all Rake (ARake) receiver is used. Also, therelationship between time-dispersion parameters and path loss is investigated. The UWB channeltransfer function (CTF) was measured in the frequency domain over a channel bandwidth of 7.5 GHz in accordance with the UWB frequency range (3.1–10.6 GHz)
