Abstract :
In this paper, we derive the perfect reconstruction condition for two-dimensional cosine-modulated oversampled filter banks. It is shown that, starting with the maximally-decimated case, a general condition for perfect reconstruction in oversampled filter banks can be obtained only in two cases. Finally, a design example is discussed.
