基于语音模态语义编码的短波通信系统性能分析OA
Performance analysis of high frequency communication system based on speech modal semantic encoding
原有短波通信体制在提升通信质量方面已接近瓶颈,进一步优化空间有限,亟需探索新方法以突破其局限.通过引入语义通信方法,设计了一种基于语音模态语义编码的短波通信系统,并将其与传统短波语音通信系统进行了通信质量性能的对比分析.仿真结果表明,在传输效率相近的情况下,所设计系统显著提升了低信噪比条件下的语音质量,在抵抗信道影响方面也表现出了更强的可靠性.
The original HF communication system has reached a bottleneck in improving communication quality,with limit-ed room for further optimization.New methods were urgently needed to overcome its limitations.An HF communication system based on speech modal semantic encoding was designed by introducing methods from semantic communication,and its communication quality performance was compared with that of the traditional HF speech communication system.Simula-tion results demonstrate that,compared with the traditional HF speech communication system,the designed system signifi-cantly improved the speech quality of low signal-to-noise ratio(SNR)conditions while maintaining comparable transmission efficiency.Additionally,it exhibited stronger reliability in resisting channel interference.
