| 摘 要： | 提出了一种基于星座聚类的MQAM调制识别新方法，运用一种改进的基于遗传算法的自适应聚类算法对MQAM星座进行重构和识别。该自适应聚类算法利用遗传算法的高效全局搜索特性，克服了模糊C-均值算法对初始聚类中心和样本输入次序敏感等不足，结合聚类有效性分析实现了聚类中心数目的自适应调整。仿真结果表明，基于该聚类算法的MQAM信号调制阶数识别方法是有效的。

| Abstract: | A novel modulation recognition method for MQAM signals is proposed.It employs a modified genetic algorithms(GA) based clustering method to rebuild and recognize constellations.The presented clustering algorithm not only overcomes the sensitivity to initial centers as fuzzy C-means with the effective global searching ability of GA,but also determines the number of clusters adaptively via validity analysis.Experiments show that this MQAM recognition method is effective. |
