Abstract

        In this paper, two different power assignment strategies for an
ultra-wideband impulse radio (IR-UWB) multi-user system are
presented and compared in terms of computational complexity. The
algorithms aim at finding the lowest possible transmission power
for each node in the network under the constraint that individual
QoS demands of all nodes are met. The first direct approach
results in a high computational complexity contradicting the
intention of building low complexity IR-UWB transceivers. We show
how the complexity of the power assignment problem can be
substantially lowered by analytical means if the network topology
is taken into consideration. Additionally, an algorithm creating
the necessary network topology is discussed.
