面向近海水域船舶通信无线信道测量与建模分析
Measurement and Modeling Analysis of Wireless Communication Channels for Ships in Nearshore Waters
摘要
Abstract
This study investigates the impact of offshore environments on the stability and signal coverage of maritime wireless communication systems by conducting measurement,analysis,and simulation of wireless channels in offshore waters.Wireless channel data are collected from typical offshore regions to extract channel characteristics and establish a channel model for maritime communication.A comparative analysis of the applicability of various path loss models is performed,along with an examination of small-scale fading characteristics in maritime wireless channels.Additionally,ray tracing techniques are used to simulate wireless channels in offshore waters.The results demonstrate that vessels and water surfaces in offshore environments significantly influence wireless channel characteristics,with the spherical earth path loss model providing a more accurate representation of path loss in offshore wireless propagation.This research provides theoretical support for optimizing the design of wireless communication systems for offshore vessels.关键词
