Synopsis:
High-speed railways (HSRs) have been widely introduced to meet the increasing demand for passenger rail travel. Investigation of wireless propagation channel is the basis for HSR communication system design, and it is thus becoming an active research field. BJTU in China is at the forefront of HSR propagation channel research. In this talk, I will briefly introduce the development of HSR in the world, particularly from the wireless propagation channel perspective. I will then focus on the propagation channel modeling. Some recent measurement campaigns are introduced, and several channel modeling approaches of HSR channel are presented. Finally, the on-going activities of LTE-Railways and some challenging issues are introduced and discussed.
