We propose a novel generalized path loss model for wireless channels, where propagation environments are suitable to be described by stochastic structures rather than being deterministically characterized. The model is combined with two dominant terms: a logarithmic function and a fractional power function of propagation distance. We validate the model by the experimental data under typical propagation...
Wireless body area network (BAN) has being a subject of growing interest in recent years. It allows the monitoring of health information with the help of sensors utilizing low power technology such as ultra-wideband (UWB) systems. Scanning the existing literature reveals that most experimental studies on BAN channel have been conducted with human object in a standing position. Alomainy et al. have...
This paper proposes a statistical model for radio propagation in indoor office buildings, where the orientations of the reflecting surfaces are not random. The important channel parameters including PAS and PDS have been derived. Multiple angular clusters were clearly observed in the PAS profiles, which have been previously presented for similar building types. The PDS profiles exhibit an exponential...
A new approach to the modeling of indoor ultra wideband radio channel is presented. We first characterize the scattering by local clutter using a set of canonical structures. Subsequently, the channel can be regarded as a continuous multimodal cost function of the scatterer locations. Each local maximum and its surrounding area are the result of closely associated objects that are part of a very similar...
