【摘要】 本文研究并设计实现了一种用于浅海水声信道多速率通信的无线/水声通信(racom)浮标,介绍了其水声通信和无线通信技术方案和工程设计与实现。本文设计的浮标综合了水声通信、DSP信号处理和无线电通信等技术,也可以用作水声通信/传感网络中的无线/水声通信(racom)网关节点。海上试验验证了本浮标总体设计方案的可行性。海上试验中,浮标无线通信距离达到15.2 km,误码率不大于10 6;除2 kbps速率外,浮标各种速率的水声通信数据传输误码率都小于1%,最大通信作用距离达到9.6 km;同时,试验也验证了浮标与水下运动平台之间的通信功能。更多还原

【Abstract】 The studies and implementations of a radio/acoustic communication buoy used for underwater multi-rate data communication in shallow-water acoustic channels are investigated.The underwater communication and wireless communication schemes as well as the engineering implementation of the buoy are introduced in detail.The underwater communication,wireless communication,and DSP signal processing techniques are integrated in this buoy.The buoy can also play the role of a radio/acoustic communication(racom) gateway node of an underwater acoustic communication/sensing network with software upgrade.A sea experiment is conducted successfully and the results verify the feasibility of the racom buoy’s design.In this experiment,the buoy’s wireless communication distance reached 15.2 km with BER of less than 10-6,underwater communication maximum distance was 9.6 km with BER of about 1% and the capability of communicating between buoy and undersea moving platform is also verified.更多还原
