Empirical capacity and the fading characteristics of ultra-wideband indoor propagation channels

This paper presents an investigation on the fading characteristics occurring in ultra-wideband (UWB) transmission in a typical indoor propagation channel. The quantities of interest are the total received power and the channel capacity, which are calculated on the basis of ray-optical propagation simulations. From the obtained results it will turn out, that the channel capacity of ultra-wideband transmission is solely dependent on the distance between transmitter and receiver and does not suffer from any influence due to multi-path propagation. Furthermore, the path loss exponent is quantified and connections to the capacity are analyzed.
