Providing stable and fast data transmission service is challenging in a high mobility wireless
communication system, where massive multiple-input multiple-output (MIMO) beamforming …

A high-speed railway system equipped with moving relay stations placed on the middle of
the ceiling of each train wagon is investigated. The users inside the train are served in two …

We discuss and propose millimeter-wave linear cell systems for signal distribution on
railway radiocommunication systems between train and trackside, and a foreign object …

A linear-cell-based radio-over-fiber (LC-RoF) system is proposed and demonstrated for
efficient mobile communication in high-speed trains without hard handover processes. The …

With ever growing mobile Internet and the explosion of its applications, users are

This paper deals with the challenging issue of the unaffordable channel training overhead in
the dense cell-free massive multi-input multi-output (MIMO) system when a high number of …

In recent years, a lot of power allocation algorithms have been proposed to maximize
spectral efficiency (SE) and energy efficiency (EE) for the distributed antenna systems …

This paper proposes a distributed antenna system (DAS)-based millimeter-wave mobile
broadband communication system for HSTs in order to meet the growing demand of high …

JPEG2000, the latest international image compression standard, owns many unique
characteristics that are different from other well-known image compression schemes such as …

In non-orthogonal multiple access (NOMA), signals of different users are independently
encoded and modulated, then superposed in the power domain before transmission. The …
