Expanded Fast H∞ Filter Toward Optimum Frequency-domain H∞ Filter for Acoustic Echo Canceller

摘要：

We study a system identification algorithm for an acoustic echo canceller. In research for system identification, a fast H1 filter (FHF) has already been developed. However, the FHF has calculation duplications and cannot finish processing in real-time with a long filter length. To overcome these problems, we propose an expanded FHF toward the optimum frequency domain for reducing the processing time. Evaluation experiments of acoustic echo canceling indicate that the expanded FHF is faster than the conventional FHF. The experimental results also indicated that the expanded FHF with restart could suppress the acoustic echo more than the conventional FHF.
