Adaptive System Identification with Tap-Assignment in Oversampled and Critically Sampled Subbands.
International Workshop on Acoustic Echo and Noise Control
Adaptation of the tap profile in subband adaptive system identification problems can further enance the efficient use of commputational resources if implemented on a DSP with an otherwise too tight benchmark performance. Here, we derive a generalisation of previous work to extend tap-assignment algorithms to a new class of oversampled filter banks with non-uniform bandwidths and different subsampling rations. We compare efficiency and adaptation results for this approach to the critically sampled case and a fullband identification with same complexity.
