Some windows with very good sidelobe behavior

Abstract

initiated the development of advanced electronic telephone line switchswitching as Manager of Technology. He was appointed an IBM Fellow ing exchanges. From 1965 to 1973, he supervised a number of projects in 1975, and has published over 30 papers and filed more than 50 on data transmission, PCM, speech processing, and advanced line patents on data transmission and digital signal processing.

An interactive platform to guide catheter ablation in human persistent atrial fibrillation using dominant frequency, organization and phase mapping

“…A Hamming window was used to reduce the amplitude of the side lobes around the DF peak in the power spectrum [21].…”

Spectral correction method based on improved flat-top convoluted window for parameter estimation of power harmonic

“…(9), the following expression is obtained The influences among adjacent harmonic components can be reduced by decreasing the peak sidelobe level of window. A low peak sidelobe level is achieved by adding additional zeros between existing zeros of the DFT window's spectrum [15]. Accordingly, to reduce the peak sidelobe level of 1P s , the following condition should be satisfied Specially, in order to enhance the flat degree of mainlobe of the parent window, the attenuation error of mainlobe δ should amount to zero.…”

“…There are mainly two approaches to design windows with great sidelobe features. One is adjusting coefficients of classical cosine windows [14,15]. The other one is time-convolutions of a specific parent window.…”

“…The sidelobe decaying rate of ( ) G λ depends on the first nonzero term in r-series [15]. Thus, according to Eq.…”

Spectral Analysis of Generalized Triangular and Welch Window Functions using Fractional Fourier Transform

“…There are numerous standard window functions that can be chosen for the prevention of spectral leakage in the signal and to provide the specified side-lobe level [7,10]. But the reduction of side-lobe leakage due to the applied window function introduces leakage from the expansion of main-lobe in ordinary frequency domain.…”
