A new window function is presented which like the well-known Hamming window offers a preferred property for use in signal spectrum analysis: the sum of window coefficients with its shifted version by half of the order is constant for the overlapped region in the time domain. In high orders, the new window has main-lobe width equal to Hamming window. For low orders, the window parameters are modified to have smaller main-lobe width compared to Hamming window, while maintaining smaller maximum side-lobe peak. The results indicate performance improvement of the proposed window compared to Kaiser and Gaussian windows. The FIR filters designed by windowing method show the efficiency of the new window. |
