高铁车厢内 RoF 无线宽带接入及其电磁环境研究
A RoF-based wireless wideband access system for high-speed train compartments and its electromagnetic environment
摘要
Abstract
This paper first proposes a RoF-based scheme for providing distributed wideband access in high-speed train compart-ments,which is characteristic of low transmitting power,distributed micro-cell coverage and multi-access points.Then,it builds a model by using the Finite-Difference Time-Domain (FDTD)algorithm software for the evaluation of the electromag-netic radiation effects in the compartments.In comparison with the conventional wireless access systems,the RoF-based sys-tem lowers the coupling electric field intensity in the compartments by 4~6 dB,while causing less power consumption,thus effectively reducing the electromagnetic interference to the on-board devices.关键词
