Prediction of Signal Distribution in Space, Time, and Frequency Domains in Radio Channels for Adaptive Antenna Applications

This chapter presents different propagation situations that influence the correlation factor in various ways. The detailed understanding of radio propagation phenomena is a keystone for the development and performance assessment of different communication systems, stationary or mobile. The chapter presents more realistic models on the basis of experimental and theoretical investigations of the propagation problem. It starts with the simple and achieves those which are more complicated but predictable regarding corresponding experiments. Then, it present the reader with some useful recommendations on how to predict a signal power in spatial (angle‐of‐arrival (AOA) and elevation‐of‐arrival (EOA)) and temporal (time‐of‐arrival (TOA) or delay spread (DS)) domains based on modified stochastic approach and verify its accuracy by comparing it with well‐known ray‐tracing and ray‐launching models and with the experiments carried in different European cities.
