Challenges Toward Wireless Communications for High-Speed Railway
Bo Ai,Xiang Cheng,Thomas Kurner,Zhangdui Zhong,Ke Guan,Ruisi He,Lei Xiong,David W. Matolak,David G. Michelson,Cesar Briso-Rodriguez +9 more
TL;DR: This work discusses in detail the main differences in scientific research for wireless communications between the HSR operation scenarios and the conventional public land mobile scenarios, and the latest research progress in wireless channel modeling in viaducts, cuttings, and tunnels scenarios.
Journal ArticleDOI
Cell-Free Massive MIMO: A New Next-Generation Paradigm
TL;DR: This paper quantifies the advantages of CF massive MIMO systems in terms of their energy- and cost-efficiency and the signal processing techniques invoked for reducing the fronthaul burden for joint channel estimation and for transmit precoding.
Journal ArticleDOI
High-Speed Railway Communications: From GSM-R to LTE-R
Ruisi He,Bo Ai,Gongpu Wang,Ke Guan,Zhangdui Zhong,Andreas F. Molisch,Cesar Briso-Rodriguez,Claude Oestges +7 more
TL;DR: To handle increasing traffic, ensure passenger safety, and provide real-time multimedia information, a new communication system for HSR is required to replace the current GSM-railway (GSM-R) technology with the next-generation railway-dedicated communication system providing improved capacity and capability.
