Bounded Brownian bridge model for UWB indoor multipath channel

Regarding a transmitter and a receiver as two fixed points of the Brownian bridge process, an ultra-wideband (UWB) multipath as a trajectory of the Brownian bridge process, all reflection points of paths situating on the surfaces of obstacles, and adopting two-value phase assumption, a bounded Brownian bridge model (BBBM) for UWB indoor multipath channel is constructed. Using BBBM to simulate a corridor environment of two glass doors with a metal grid inside, several characteristic parameters of UWB channel are obtained. The power delay profiles (PDPs) are similar to the results from other experiments
