VHF data exchange system (VDES) is an emerging maritime communications standard that is meant to provide ship-to-shore, shore-to-ship, and ship-to-ship information services. VDES also includes a satellite component to extend the service coverage also to the high sea. Ships can receive important information via VDES and access this service via satellite when they are far from the shore. This paper uses data taken during a measurement campaign to develop an ON-OFF model for the VDE-SAT downlink channel taking the multipath effects caused by sea reflections into account. This model has been used to evaluate the impact of packet-level forward error correction (FEC) schemes (i.e., ideal codes, RaptorQ codes, and 2-Dimension Reed-Solomon codes) to further protect transmissions from deep fading events and to evaluate the impact at the transport level considering the possibility to adopt the transmission control protocol (TCP) for a file map delivery service.

卫星前向 VDES 信道建模及其对高层性能的影响

VHF 数据交换系统 (VDES) 是一种新兴的海上通信标准,旨在提供船对岸、岸对船和船对船信息服务。VDES 还包括一个卫星组件,以将服务覆盖范围也扩展到公海。船舶可以通过 VDES 接收重要信息,并在远离海岸时通过卫星访问该服务。本文使用测量活动中获取的数据为 VDE-SAT 下行链路信道开发了一个 ON-OFF 模型,并考虑了海面反射引起的多径效应。该模型已用于评估数据包级前向纠错 (FEC) 方案(即理想代码、RaptorQ 代码、
