摘要
从波形这一原始信号特征来分析信号细微特征,研究建立一种波形骨架提取的信号细微特征识别模型,强调利用主曲线来提取波形的原始骨架,采用分形进行骨架比对,借此识别不同信号源发出的信号。依据信号源细微特征产生机理,设计仿真实验,验证波形骨架提取的信号细微特征识别模型可靠有效。
Fine signal characteristic is analyzed from the aspect of wave, the original signal characteristic. The model of picking up wave skeleton to identify fine signal characteristic is put forward, by which principal curve is used to pick up the original skeleton of wave. Fractal compares the skeleton in order to recognize the signal emitted from different sources. Based on the mechanism of production of fine characteristic, simulation experiment is designed, and the result explains the reliability and validity of the model
