提出了一种基于支持向量机的多类模拟调制方式识别算法。该算法通过分析模拟调制信号的特点，提取有效的特征向量以区分不同的调制方式，并基于支持向量机和判决树分类思想，将特征向量映射到高维空间中加以分类。-A support vector machine based on the many types of analog modulation recognition algorithm. The algorithm by analyzing the characteristics of analog modulation signal to extract effective feature vector in order to distinguish between different modulation methods, and based on support vector machines and decision tree classification of ideas, will feature vector is mapped to the high-dimensional space to be classified.
