Speech signal synthesis based on the filter banks in finite and polynomial rings

Alexander M. Krot, Vadim O. Kudryavtsev

High quality filters are essential part of vocoders. By means of filter banks structures we can combine modern DSP algorithms with hardware realizations having many parallel identical devices. This paper proposes digital filter realization based on filter bank structure suitable for hardware realization.
