Abstract :
A block filter implementation technique for uniform filter banks is proposed in this paper. By applying block filters into decimation and interpolation filters, it is shown that down and zip samplers are cancelled out in respective filters. Furthermore, by applying block filters into uniform filter banks, significant reduction for computational complexity is achieved since prototype filter can be shared in each channel implementation. Also, it is shown that the proposed implementation is a reconfigurable structure in term of filter order variation
