摘要：

文中提取了反应调制类型差异的6个特征参数。这6个特征参数是对传统特征参数的改进,运算简单且判决门限容易确定。构建了基于决策论算法的分类器,对典型的13种数字模拟信号进行了调制识别。仿真结果表明,该分类器具有良好的调制分类识别性能。

关键词: 决策论, 调制识别, 特征参数

Abstract:

The six character parameters reflecting the differences of the modulations are extracted.These six character parameters are improvements of traditional parameters,which are relatively simple in computing methods and clear decision threshold.The classifier based on decision-theoretic algorithm is established,and thirteen typical digital and analog signals are identified.Simulation result shows that this classifier has better performance for modulation recognition.

Key words: decision theory;modulation recognition;character parameters
