Proportionate Subband Adaptive Filtering

摘要：

This paper explores the use of proportionate adaptation and subband adaptive filtering techniques for applications involving colored excitation and the modeling of sparse impulse response. It has been shown that proportionate adaptation technique is capable to deal with sparse environment, while subband adaptive filtering technique provides good convergence performance under colored excitation. This paper integrates both crucial functionalities into a single algorithm for applications like network and acoustic echo cancellation, and feedback cancellation in hearing aids. The efficacy of the proposed algorithm is examined and validated via simulations.
