چکیده (انگلیسی):

In wireless communications, where sensors operate on batteries,
the energy consumption must be reduced while considering the
communication range and data rate requirements. In this context we
analyze and compare, in this study, the UWB and TR-UWB system in
terms of the total energy consumption. So, for that, we develop an
analytical model to estimate the energy consumption of a UWB system
using a TR technique. We then compare the consumption of a TR-UWB
system and a UWB system in two different propagation environments. We
show that the TR-UWB system is more energy efficient than the UWB
system in the chosen environments for LOS. However in case of NLOS,
TR-UWB is more efficient when we use a bi-symbol modulation for
different ranges of distance in both environments.
