A new path-gain/delay-spread propagation model for digital cellular channels.

Derives a statistical model for the distribution of rms delay spread (Trms) with a cellular environment. Arguments that Trms should be lognormally distributed at any given distance; What the standard propagation model for cellular communications represents; Correlation between delay spread and shadow fading; Evidence supporting the findings of a compact statistical model for the joint distribution of path gain and delay spread.
