Abstract-- Practical and low complexity implementation of
receivers is of vital importance for the successful penetration of
the ultrawideband (UWB) technology. Energy detector receiver
is an attractive solution for UWB signal reception trading off
complexity with performance. In this paper, joint estimation
of the optimal threshold, synchronization point, and integra-
tion interval for energy detection based ultrawideband signal
reception with on-off keying (OOK) modulation is developed.
Suboptimal reception derived from the optimal solution is also
given for practical implementations. Gaussian approximation of
the received signal statistics enables low complexity solutions at
the expense of some performance degradation. The performances
