Lower error bound for oversampled subband adaptive filters

Weiss, Stephan and Stenger, Alexander and Rabenstein, Rudolf and Stewart, Robert (1998) Lower error bound for oversampled subband adaptive filters. Electronics Letters, 34 (16). pp. 1555-1557. ISSN 0013-5194

Abstract

The authors evaluate error performance limitations in oversampled subband adaptive filter applications based on an analysis of aliasing in the subband signals. The power spectral density of the minimum error signal is given by the aliased signal components. The presented analysis closely agrees with simulation results.
