摘　　要：海上无线通信是e-航海战略实施和发展的基础,现有的海上通信技术在广泛用于海上船岸与船船之间的数据通信中存在诸多限制。提出的海上甚高频宽带数据传输技术方法,改变了现有的海上甚高频的通信方式,通过分析海上甚高频频段特性,构建了基于OFDM调制方式的海上甚高频宽带数据传输模型。仿真和实验表明,该方法能够明显提高现有海上甚高频频段的通信速率,并且能够获得较低的误码率。Marine wireless communication is the base of actualizing and developing e-navigation strategy, but the existing means of maritime communication have many limits in their widespread applications, especially between in ship-shore and ship-ship communication. We propose a broadband data transmission approach in maritime VHF, which can change the communication ways of maritime VHF. We also build a broadband data transmission model in maritime VHF based on OFDM by analyzing VHF spectrum characteristics. Simulations and experiments show that the proposed approach can obviously increase communication speed of maritime VHF and has lower BER.
