Generalized Cosine Windows
Blackman, flat top, Hamming, Hann, and rectangular windows are all special cases of the generalized cosine window.
凯塞窗
凯塞窗旨在最大化主瓣能量与旁瓣能量之比。
Chebyshev Window
The Chebyshev window minimizes the mainlobe width for a particular sidelobe level and exhibits equiripple sidelobe behavior.
