| Abstract: |
This paper presents a set of windows, called sum-cosine windows, whose first sidelobe level varies from -39·30 to -67·66 dB, while the peak sidelobe offers -39·30 to -63·12dB attenuation. The asymptotic decay rate of the sidelobe envelope ranges from 12dB per octave to 36dB per octave. However, the main-lobe width of these windows falls in between Hamming and Blackman windows and Blackman windows and the optimum windows, proposed by Harris and Nuttall. The distinct advantage of these windows is their simple form, resulting in easy implementation, compared to the near-optimum windows proposed by Kaiser. [ABSTRACT FROM AUTHOR] |
