Abstract

A critical aspect in the analysis, design and implementation of wireless communication systems and networks is the thorough understanding of the nature and characteristics of the propagation medium. Its study has been a key research topic from the very beginning of wireless communications but it has proliferated in the last two decades due to the extreme growth of wireless technologies and the increasing demand of wireless services and applications. This paper identifies current trends in the modeling, simulation and estimation of the wireless propagation channel, addresses open issues in the area and discusses future research perspectives. Within this context, we provide an overview of state-of-the-art research, review selected methods and techniques in recent scientific and patent literature and present theoretical advances and underlying technologies used thereof.
