In this method, eigen-decomposition does not have to be used, and the direction spectrum is the power spectrum in common sense (it can be used to estimate signal power).

本方法不需要特征分解，并且得到的是通常意义上的功率谱(可用于估计信号的能量)。

The main studied topic of spatial spectrum estimation is the direction of arrival (DOA) of spatial signals.

对信号波达方向(doa)的估计是空间谱估计研究的主题。
