The parameters of various windows have been determined and the performance of the truncated Taylor family, the raised-cosine family, Kaiser's modified zeroth-order Bessel family, sum-cosine and Blackman windows have been compared. © 1977, The Institution of Electrical Engineers.

A set of windows, whose normalised main lobe widths fall between those of Hamming and the sum-cosine window, are developed. The windows are compared with Kaiser's near optimum zeroth-order Besssl windows. The results show that the new windows yield 4 to 9 dB improvement in the first sidelobe gain, and the improvement in maximum sidelobe gain varies from 2·8 to –085 dB, compared with that of Kaiser windows. The energy in the main lobe of Kaiser windows is at most 0·005% larger than that of the new windows. The distinct advantage of the windows is their very simple form, similar to that of a Hamming window. © 1975, The Institution of Electrical Engineers. All rights reserved.

Synthesis of windows from raised-cosine pulse

A simple window that yields 6 dB improvement in the first sidelobe gain, with almost no loss in the maximum sidelobe 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. © 1974, The Institution of Electrical Engineers. All rights reserved.
