The reduced spectral leakage into the side-lobes of a window function is obtained with a more tapered window; with the same length; which has lower side lobes. The classical windows can realize these characteristics by using one parameter. To obtain a tradeoff between good frequency resolution and acceptable spectral leakage we can use a smoothing time window function. The window functions; with increased order of continuity can be obtained by using grouped Bspline functions. We optimize the power spectral density estimation by using three control parameters. © 2020; Politechnica University of Bucharest. All rights reserved;
