Random Walk and Wave Propagation
Yoshio Karasawa AP2019-190
Abstract (in Japanese) (See Japanese page) 
(in English) While doing a random walk, we visit some basic probability distributions that appear in radio wave propagation models. Radio wave propagation, particularly multipath propagation in mobile communications, is a phenomenon originally born in a random stochastic process, so it can be said that it is a random walk itself. Here, we start with a random walk in one-dimensional space / two-dimensional space and reach a multidimensional space. The probability that the random walk returns near the starting point decreases as the number of dimensions of the space increases. This feature is utilized in space diversity as a potential countermeasure against fading. If you are interested in what it means, please read this report.
