Meaning: The self-correlation function and powerspectrumdensity Function of a power-typed signal compose a FT pair.
上式表明: 功率型信号的自相关函数与其功率谱密度函数构成傅立叶变换对。

This algorithm has utilized the signal to carry on the signal characteristic that Fourier includes in the density of the powerspectrum after Fourier transform.
算法利用了信号进行傅里叶变换后功率谱密度中所包含的信号特征在基带完成,并用软件实现。
