| 根据美军标MIL-STD-188-141A的规定，8FSK信号的解调是短波自动链路建立(ALE)系统的一项关键技术。通过把图像分割和聚类分析方法应用于8FSK信号的频谱分析，提出了基于模式识别的解调算法。测试结果表明，该算法对白噪声不敏感。 |

| Abstract: |
| According to American military standard MIL-STD-188-141A,demodulation of 8FSK is a key technique in high frequency(HF) automatic link establishment(ALE) system. Under the application of image segment and clustering analysis methods into 8FSK signal's spectrum analysis, a demodulation algorithm based on pattern recognition is proposed. Test resut indicates the algorithm is insensitive to white noise. |
