Abstract

Design procedures for stable, causal and perfect reconstruction IIR parallel uniform DFT filter banks (DFT FB's) are presented. In particular, a family of IIR prototype filters is a good candidate for DFT FB, where a tradeoff between frequency selectivity and numerical properties (as measured by the Weyl-Heisenberg frames theory) could be made. Some realizations exhibiting a simple and a massively parallel and modular processing structure making a VLSI implementation very suitable are shown. In addition, some multipliers in the filters (both the analysis and synthesis) could be made powers or sum of powers of 2, in particular for feedback loops, resulting in a good sensitivity behavior For these reasons as well as for the use of low-order IIR filters (as compared with conventional FIR filters), the overall digital filter bank structure is efficient for high data rate applications. Some design examples are provided.
