水声语音通信性能的实时感知方法与关键技术研究

Underwater acoustic communication channel is a complex and changeable communication channel. Real-time communication performance evaluation is of great value to underwater acoustic communication system. Speech quality of the terminal is largely determined by physiologic and psychological factors of the receiver. So conventional communication performance parameters has great limitations for underwater acoustic voice communication. In view of the shortcomings of the conventional performance parameters, this research introduces speech quality evaluation into underwater acoustic voice communication performance evaluation model, and establishes performance evaluation model based on speech quality. This research contents include: 1) the relevance and consistency between speech characteristic parameters and speech quality; 2) the hidden information transmission technology of voice watermarking; 3) deconstruction of E-MODAL in underwater acoustic voice communication system; 4) evaluation model of underwater acoustic voice communication performance based on speech characteristic parameters; 5) E-MODAL evaluation model of underwater acoustic voice communication performance. The evaluation model of the research can calculate performance of underwater acoustic voice communication system in real time, reveal the effectiveness of the communication system, and allocate communication bandwidth reasonable. The evaluation model of the research has important theoretical value and practical value for the evaluation of underwater acoustic voice communication system and the overall design.

水声通信信道是一个复杂多变的通信信道，实时的通信性能评估对水声通信系统具有重要的价值。水声语音通信着眼于语音信息的传输，终端恢复语音的质量很大程度上是由接收者的生理和心理因素决定的，传统通信性能评价指标对于水声语音通信具有很大的局限性。针对传统性能评价指标的不足之处，本课题将语音质量评测引入到通信性能评价模型中，建立基于语音质量的水声语音通信系统的性能评估模型。研究内容包括：1）语音特征参数与语音质量相关度与一致性的测评；2）语音水印的隐藏信息传输技术；3）E-MODAL模型在水声语音通信系统中的解构；4）基于语音特征参数的水声语音通信性能评测模型；5）水声语音通信性能的E-MODAL评测模型。课题的评测模型可实现对水声语音通信性能的实时感知，监测通信制式的有效性，合理使用通信带宽，对水声语音通信系统的测评以及整体设计都具有重要的理论价值与实践价值。
