Design of Oversampled Uniform DFT Filter Banks with Reduced Inband Aliasing and Delay Constraints
(2001) Sixth International Symposium on Signal Processing and its Applications (ISSPA 2001) 1. p.104-107- Abstract
- Subband adaptive filters have been proposed to avoid the drawbacks of slow convergence and high computational complexity associated with time domain adaptive filters for acoustic echo cancellation. Subband processing introduces transmission delays caused by the filter bank and signal degradations due to aliasing effects. One efficient way to reduce the aliasing effects is to allow a higher sample rate than critically needed in the subbands and thus reduce subband signal degradation. We suggest a design method, for a uniform DFT filter bank with any over sampling factor, where the total filter bank group delay may be specified, and where the aliasing and magnitude/phase distortions are minimized.
