Hybrid Filter Banks optimization design using total least square solving

This paper introduces a simple method for designing hybrid filter banks for A/D converters with mixed distortion/aliasing optimization of channels using total least-squares solving. Distortion/aliasing discipline induced by HFB itself is the principal goal so that a mixed optimization algorithm related to distortion and aliasing errors is introduced. By this optimization using total least-squares the design method take the imprecision of analog analysis filter into account and hybrid filter banks are approximately PR. Through the simulation, several design examples are included, illustrating the properties of the proposed filter banks.
