Abstract-- Inter-symbol interference (ISI) is known to be a
major factor complicating the realization of high data rate ul-
trawideband (UWB) communications. In the literature, methods
for suppressing ISI in UWB systems employing complex receivers
exist. In this paper, considering the low cost requirement along
with the need for high data rates, we propose a modified,
on-off keying (OOK) based low complexity energy detector
receiver capable of eliminating ISI. The presented receiver utilizes
an ISI cancellation algorithm depending on decision feedback
equalization (DFE) and it is advantageous in that it does not
suffer from error propagation. The results obtained demonstrate
a considerable gain in the symbol detection performance of the
