Performance Analysis of HF Communication System Based on Text Modal Semantic Encoding

With the increasing demand for the reliability of HF communication, there is an urgent need to explore new methods to enhance its performance. We design an HF communication system based on text modal semantic encoding by introducing the relevant methods of semantic communication. A comparison is made between the proposed system and traditional HF communication system using BLEU score and semantic similarity score. Simulation results demonstrate that the proposed system achieves BLEU scores and semantic similarity scores comparable to the traditional system at a lower signal-to-noise ratio (SNR), significantly enhancing the reliability of HF communication.
