摘要：The knowledge of the propagation channel properties is an important issue for a successful
design of ultrawideband (UWB) communication systems enabling high data rates in short-range
applications. 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 the
path loss exponent are derived for the direct path and for a Rake receiver structure, examining
the maximum multipath diversity gain when an all Rake (ARake) receiver is used. Also, the
relationship between time-dispersion parameters and path loss is investigated. The UWB channel
transfer 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).
