基于FPGA的水声信号通信系统

Underwater data exchange system based on FPGA

文章提出了一套潜水员手语辅助通信系统的设计方案,方案应用时频分集、跳频扩频等水声通信体制,采用2FSK调制方式,以手语指令形式进行通信,其核心在于信号的传送,故不涉及相关手语内容,并结合当下流行的FPGA技术对系统进行开发设计。该系统实现了信号数据的水下传输,可进一步通过配合语音合成和语音识别技术来保证潜水员水下通信的可靠性和简易性。

A design of underwater data exchange system with sign language for diver is proposed in view of the limitations of diver sign language communication in application .The technologies of time-frequency diversity and frequency hopping （FH） are applied in this system .Communication is in the form of diver sign language instruction using 2FSK modulation and demodulation based on FPGA .The core is the transmission of the da-ta ,and the relevant sign language content is not involved .The system realizes the underwater data transmis-sion of diver sign language instruction and guarantees the reliability and simplicity of underwater acoustic com -munication with speech synthesis and speech recognition technology .
