Impulse systems do not undergo the multipath destructive interference that manifests itself as Rayleigh fading prevalent in continuous wave systems, but rather show up as delayed replicants of the direct impulse. In this paper, the model for impulse signals propagation over a plane earth is proposed. The condition for direct pulse and its replicant overlapping with each other is investigated. The...
A simulation of UWB impulse signals propagation within an indoor non-line-of-sight (NLOS) environment is addressed in this paper. The transmitter and the receiver are placed in two rooms respectively with a concrete wall blocking the line-of-sight (LOS) propagation path. The radiation pattern and the polarization pattern of transmitting/receiving antenna are modelled. The corresponding transient electromagnetic...
Nowadays, the path loss characteristics of UWB signals is widely investigated in the world for providing the channel model to UWB system. In this study, the propagation rules for UWB signals in indoor line-of-sight (LOS) environment are proposed. The relationship between multipath overlapping and the path loss is analyzed mathematically in time-domain. A new 5 rays path loss calculation method, which...
