According to the relationship between autocorrelation function and its spectral density, a new type of decision tree method based on signal analysis theory is proposed in this paper.
该文根据自相关函数与谱密度函数之间的对应关系，提出了一种新的基于自相关函数的决策树归纳学习算法。

At last, making use of the plotting function of MATLAB, the paper carries out simulation analysis from three aspects: auto-correlation function, spectrum and fuzzy function.
