基于LabVIEW的水声通信网络节点技术研究

The Technology of Underwater Acoustic Communication Network Nodes Based on LabVIEW

随着军事和民用领域对水声通信和水声通信网需求不断加大,分布式水声通信技术的构建与应用成为水声通信研究的热点.采用LabVIEW虚拟仪器编程软件与美国NI的CompactRIO硬件模块,构建4FKS-FH水声通信调制解调器(MODEM),并设计了自动增益控制、同步跟踪以及信道编码:交织与卷积码等模块.通过多次水池及海试试验,验证了该水声MODEM性能的有效与可靠性,为构建更为复杂的多节点水声通信网络提供坚实的基础.

Nowadays,the construction and application of underwater acoustic communication networks has received much focus in the research area of underwater acoustic communication technology as both the military and the commercial demand of underwater acoustic communication and networks has been expanding.In this paper,the software LabVIEW and the hardware module C-RIO were used together to build up a underwater acoustic communication MODEM based on the principles of 4FKS-HF,and to design different types of modules to realize the functions of automatic gain control,synchronous tracking,channel interleaving and coding.The high security of the acoustic MODEM under the structure of multi-hop network topology has been proved by several experiments in the cistern and sea,laying the substantial foundation for the construction of the more complicated multi-node underwater acoustic communication network in the future.
