Low-Complexity Adaptive Filtering Implementation for Acoustic Echo Cancellation
Blekinge Institute of Technology, School of Engineering, Department of Signal Processing2006 (English)Conference paper (Refereed) Published
Acoustic echo cancellation is generally achieved with adaptive FIR filters. Due to the often large dimensionality of the adaptive filters, required to model rooms with standard reverberation time, the adaptation process can be computationally demanding. This paper presents a block based selective updating method which reduces the complexity with nearly a half in practical situations, while showing superior convergence speed performance as compared to conventional partial update complexity reduction schemes.
