TLDR
In this paper, a simple window that yields 6 dB improvement in the first sidelobe gain with almost no loss in the maximum sidclobe gain, compared with that of Kaiser's near optimum zeroth-order Bessel window, is developed.
Abstract: 
A simple window that yields 6 dB improvement in the first sidelobe gain, with almost no loss in the maximum sidclobe gain, compared with that of Kaiser's near optimum zeroth-order Bessel window, is developed. The main-lobe energy of Kaiser's window is about 0.00078% more than that of the new window. The distinct advantage of the window is its very simple form similar to that of a Hamming window.

A set of sum-cosine window functions

K.M.M. Prabhu
- 01 Jun 1985 - 
TL;DR: A set of windows, called sum-cosine windows, whose first side-lobe level varies from −39-30 to − 67-66dB, while the peak sidelobe offers −39 to − 6312dB attenuation are presented, resulting in easy implementation compared to the near-optimum windows proposed by Kaiser.

Data Windows in Digital Signal Processing—A Review

K.M.M. Prabhu, +1 more
- 01 Jan 1980 - 
TL;DR: The paper presents a number of data windows that are commonly used in digital signal processing and their distinctive features and their use in power spectral estimation, digital filtering and pulse compression radar are discussed.

Optimised data windows

K.M.M. Prabhu, +1 more
- 03 Jan 1980 - 
TL;DR: In this paper, an optimised Blackman window that gives better sidelobe attenuation with almost the same mainlobe energy content as the original blackman window is presented, and the new coefficients yield about 10 dB improvement in the first sidelobe level and almost 45 dB in the maximum sidelobe levels.

Binary windows for the discrete Fourier transform

F.C. Marshall, +1 more
TL;DR: An efficient structure is suggested for the frequency-domain windowing of discrete Fourier transforms in which multiplications are replaced by shifts in the position of the binary point.
