Power delay profile in a cluttered environment

A stochastic-ray model of wave propagation based on the theory of random walks that accounts for only two parameters: the amount of clutter and the amount of absorption in the environment is considered. This model applies to indoor and outdoor environments, characterized by a large number of (small) scattering objects. Examples are microcells for personal communication and networks of multihop wireless sensors or laptop computers. We extend our previous results on narrowband signals to impulse waveforms, deriving a closed form solution for the power delay profile of the received signal.
