On the power delay profile and delay spread for physics-based simulated mobile channel

Physics-based simulation of radio channels offers a powerful technique for propagation analysis and even evaluation of antennas. In this paper, it is shown how the power delay profile (PDP) and its moment, the delay spread, can be evaluated from physics-based channel data. The situation is different to that of the measured channel. The simulated channel contains more information, including information that cannot be extracted from the measured channel. Different processing of this data gives different PDPs and moments, and some of the issues are presented here.
