Abstract :
A method for calculating the coefficients of the Gabor expansion in the context of oversampling is presented. The method is based on the concept of frames and utilizes the Zak transform. The Zak transform further highlights the meaning and importance of frames in the context of oversampling and other aspects of signal representation by means of nonorthogonal bases
