Experimental UWB Propagation Channel Path Loss and Time‐Dispersion Characterization in a Laboratory Environment
International Journal of Antennas and Propagation, 2013•Wiley Online Library
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 …

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).
