摘要：

The reduction of the spectral leakage into the side-lobe of a window function is to obtain a more gradual window, with the same length, which generates a lowering of the side lobes amplitude. The usual windows can control these characteristics by using one parameter. To reduce the spectral leakage, a window function in the time domain is used to shape that decrease more gradually toward zero. We propose to use grouped B-spline functions to obtain window functions, with increased order of continuity. The power spectral density estimation is optimized by using three control parameters.
