Accurate Prediction of Available Path Number and Delay Spread Considering Path Existence Probability in Wideband Mobile Propagation

To designing higher-speed digital mobile communication systems, we must predict the multi-path propagation characteristics more accurately. Available path number and delay spread are effective indicators that make it easy to evaluate multi-path propagation. In this paper, we propose a novel delay profile model that can predict the available path number and the delay spread accurately due to its inclusion of path existence probability and its consideration of city structure characteristics such as building height. We clarify its validity by field measurement results.
