This paper evaluates the applicability of the DVB-S2 standard in railway environments, where the most peculiar impairment is the periodic deep fading caused by power-supply arches distributed along the rail tracks. This effect induces a link loss every time the train antenna undergoes a power arch and cannot be counteracted with transmission power. Therefore, we propose and investigate the use ...

DC voltage utilization and AC harmonics are important evaluation indexes for Auxiliary Power Converter in Railway Applications. To improve the above two indicators, a novel switch-mode modulation method quasi-PR control strategy Buck-H three-phase inverter is proposed this paper. The integrates side filter circuit into Buck circuit, which reduces volume of capacitor improves filtering effect. T...

Railway wireless communication has become an indispensable part to provide the reliability and safety of the railway operation as well as the improved railway services. In addition, advanced mobile communication technologies have triggered new railway customer services. Thanks to many benefits of the 4-generation mobile communication technology, long-term evolution (LTE), this technology is one...
