Filter Bank Design for Subband Adaptive Filtering Applications
Responsible organisation
2001 (English)Report (Other academic)
Abstract [en]

Subband adaptive filtering has been proposed to improve the convergence rate while reducing the computational complexity associated with time domain adaptive filters. Subband processing introduces transmission delays caused by the filters in the filter bank and signal degradations due to aliasing effects. One way to reduce the aliasing effects is to impose oversampling in subbands rather than critical sampling and thus reduce signal degradation. By doing so, additional degrees of freedom are introduced for the design of filter banks which may be optimally exploited. In this report, a design method for modulated uniform filter banks with any oversampling is suggested, where the analysis filter bank delay and the total filter bank delay may be specified, and where the aliasing and magnitude/phase distortions are minimized.
