Abstract :
Wireless communication systems require proper understanding of the spatial and temporal characteristics of the propagation channel. This paper presents a geometrical based single bounce model for indoor ultra wideband (UWB) communication in which the multipath reflection is accounted by uniform distribution of scatterers placed in the clusters of elliptical region around the transmitter (Tx) and receiver (Rx). Analytical expressions for the Angle of Arrival (AoA) and Time of Arrival (ToA) probability density functions (pdfs) have been derived for the proposed model. These expressions have been validated through simulation and the results are also compared with the measured data available in literature.
