DCT
实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见,经DCT低通滤波后,图像变得很模糊。因为DCT是FFT取其实部,能量减少,因此图像变得很模糊,没有经FFT滤波后的效果好。
经DCT高通滤波后的图像:
经DCT高通滤波后,图像的低频部分被滤除掉,图像变黑,只有边缘的痕迹可见。

ESPRIT_DOA
说明: ESPRIT方法进行DOA估计,各种参数见程序内部的参数设置,只是简单的ESPRIT程序,而非修正的ESPRIT方法(ESPRIT DOA estimation methods, see the program within the parameters set of parameters, but simply the ESPRIT program, rather than the ESPRIT method of correction)
