Kertas kerja ini membentangkan kaedah yang berkesan untuk mengira bingkai dwi pengembangan Fourier jangka pendek (STFE) dalam l2(Z). Berdasarkan hubungan antara tetingkap prototaip yang digunakan untuk menjana bingkai dan tetingkap dwi prototaip yang digunakan untuk menghasilkan bingkai dwi dalam STFE, dua kaedah berangka yang berguna dengan pengendali bingkai terhingga dicadangkan untuk mendapatkan bingkai dwi sokongan terhingga dalam perumusan domain masa. Kaedah boleh digunakan untuk membina berbilang STFE (MSTFE) yang sesuai untuk analisis kekerapan masa, sintesis dan pengekodan isyarat tak pegun masa diskret. Keputusan simulasi berangka diberikan untuk mengesahkan keberkesanan pengiraan bingkai dwi.

Shigeo WADA, "Effective Calculation of Dual Frame for the Short-Time Fourier Expansion" in IEICE TRANSACTIONS on Fundamentals,
vol. E85-A, no. 5, pp. 1111-1118, May 2002, doi: .
Abstract: This paper presents effective methods to calculate dual frame of the short-time Fourier expansion (STFE) in l2(Z). Based on a relationship between the prototype window used for generating a frame and the dual prototype window used for generating a dual frame in the STFE, two useful numerical methods with a finite frame operator are proposed to obtain finite support dual frames in time domain formulation. The methods can be used to construct the multiple STFE (MSTFE) suitable for a time-frequency analysis, synthesis and coding of discrete-time nonstationary signals. Numerical simulation results are given to verify the effectiveness of the calculation of dual frame.
