On variable overlapped windows and weighted orthonormal bases
Bruce W. Suter, Mark E. Oxley · IEEE Transactions on Signal Processing · 1994
A generalized lapped orthonormal transform (GLOT) formulation is presented for the analysis and synthesis of signals. This formulation is composed of a variable width window and a linear combination of weighted orthonormal functions. Tradeoffs in the specification of windows are examined. A sinusoidal example is considered, and a fast algorithm is provided for its evaluation.>
