Abstract :
A site-specific convex pyramidal beam tracing model of ultrawideband (UWB) indoor propagation channels is described in detail. The model is fast and accurate, since it does not need to apply nontrivial and costly tests to determine all the existing rays between the transmitter and receiver. Predictions from the model are compared with those from corresponding measurements, performed under line-of-sight (LOS) and nonline-of-sight (NLOS) conditions. A good agreement is displayed between predicted and measured impulse responses, as well as of some derived parameters (average power, mean delay, and delay spread), as they vary with the distance between the transmitter and the receiver.
