Abstract
It is, therefore, an object of the present invention to provide a structure and method of processing signals, which includes transforming a signal into subbands by applying a forward discrete wavelet transform (FDWT) to the signal, partitioning the subbands into overlapping subband subsets, inverse transforming the overlapping subband subsets into signal subsets by applying at least one inverse discrete wavelet transform (IDWT) to the overlapping subband subsets, and combining the signal subsets to reproduce the signal. The IDWT is applied to all of the subband subsets in parallel.
