Adaptive system identification with tap-assignment in oversampled and critically sampled subbands

Research output: Chapter in Book/Report/Conference proceedingConference contribution book

Abstract

Adaptation of the tap profile in subband adaptive system identification problems can further enhance the efficient use of computational resources if implemented on a DSP with an otherwise too tight benchmark performance. Here, we derive a generalization of previous work to extend tap-assignment algorithms to a new class of oversampled filter banks with non-uniform bandwidths and different subsampling ratios. We compare efficiency and adaptation results for this approach to the critically sampled case and a fullband identification with same complexity.
