Guest editorial: special issue on high mobility wirelesscommunications

Abstract

he high-speed railway and high-way networks are now expanding at a phenomenal speed in China

and in many other parts of the world. The related broadband wireless communication over high-speed trains and highway vehicles is a very challenging task due to hostile transmission channel conditions. The demand for such services is growing rapidly, following the proliferation of laptop/tablet computers and smart phones. This motivates the research on wireless communications in the high mobility environments.

This special issue aims at putting together the new achievements and developments in this field. There are

11 papers in this special issue, which have been organized into three thematic groups. The first group of4 papers deals with the rapidly time-varying channelmeasurement, modeling and estimation. The second group of 3 papers addresses the Doppler effects andsignal detection. The last group of 4 papers contributesto the relays, networking coding, and the fast handover schemes for high mobility scenarios.
