摘　　要：为满足有效可靠的水声语音通信需求,针对语音信号和水下信道的特性,以TI公司的DSP芯片TMS320VC5416和DVSI公司的AMBE-2000芯片为基础,设计了一种适用于水下的小型数字语音通信系统方案,建立了通信系统的整体硬件结构,并对各关键功能模块进行了性能调试和分析;通过对系统的测试和性能分析,硬件系统运行稳定可靠,为实现水声语音通信搭建了良好的硬件平台。In order to satisfy the efficient and reliable requirement of underwater acoustic speech communication, aiming at the speech signal and the submarine channel＇s characteristic, taking TI Corporation＇s DSP chip TMS320VC5416 and DVSI Corporation＇s AMBE-2000 chip as the foundation, one project of the pocket digital underwater speech communication system is designed and developed in this paper. The whole hardware architecture of the communication system is constructed and the essential function module performance is debugged and analyzed. Tested results show that this system is stable and reliable, build a good hardware platform for underwater acoustic speech communication.
