Abstract-- UWB pulses are the unique labels of UWB systems.
This paper investigates the role of pulse systematically and
highlights the central position of the pulse in UWB systems.
Four system properties related closely to the pulse are discussed:
propagation properties, capacity, interference to existing systems
and performance of correlation receivers. The properties of
pulses which function directly on every aspect are highlighted.
Novel viewpoint is provided for the evaluation of capacity and
interference. Suggestions are given on the pulse design, with
emphasis on the whole system performance.
I. INTRODUCTION
UWB systems are defined with respect to the spectrum
property of the transmitted signals [1], rather than any other
properties. This indicates the importance of the pulse in a
UWB system. Seemingly, UWB provides a method of spec-
