Minimum-Bias Windows for High-Resolution Spectral Estimates

% Usage window=papouliswin(SIZE of WINDOW);
% The variance of the resulting estimate is smaller than that obtained
% with the known windows of the same size.
% Details of the property of the window can be found in
% A. Papoulis, “Minimum-bias windows for high-resolution spectral es-
% timates,” IEEE Trans. Inform. Theory, vol. IT-19, no. 1, pp. 9-12
