| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a low-distortion noise canceller with no auxiliary filter. The coefficient adaptation stepsize is controlled by two factors; an estimated signal-to-noise ratio (SNR) at the primary input and a relative coefficient magnitude normalized by the reference power. The SNR is estimated based on the noise replica and the output. The SNR-controlled stepsize provides robustness to interference of the desired speech to the error. A newly developed partitioned power-normalized proportionate normalized least-mean-squares (PP-PNLMS) algorithm stabilizes coefficient fluctuations caused by a delay in recursive operation in the SNR estimation. Subjective evaluation results have demonstrated statistically significant difference in the low-SNR scores over a 3GPP noise suppressor. |
