The rapid development of high-speed railways (HSRs) puts forward high requirements on the corresponding communication system. Millimeter wave (mmWave) can be a promising solution due to its wide bandwidth, narrow beams, and rich spectrum resources. However, with large number antenna elements employed, energy-efficient solutions at mmWave frequencies are in great demand. Based HSR system multipl...
Carbody vibrations of high-speed train caused by dynamic unbalance of underframe suspended equipment
The vigilance of the driver is important for railway safety, despite not being included in the safety management system (SMS) for high-speed train safety. In this paper, a novel fatigue detection system for high-speed train safety based on monitoring train driver vigilance using a wireless wearable electroencephalograph (EEG) is presented. This system is designed to detect whether the driver is...
With the fast development of high-speed railway (HSR), the demand for mobile communication on high-speed trains is increasingly growing. This leads to significant attention on the study of resource management in HSR wireless communications with limited bandwidth. Resource management is a challenging problem due to heterogenous quality of service (QoS) requirements and dynamic characteristics of...
