| Abstract(in English) | In this paper, we conduct an analysis for reduction of musical noise in integration method of microphone array signal processing and nonlinear signal processing. In these days, for better noise reduction, integration methods of microphone array signal processing and nonlinear signal processing have been researched. However, nonlinear signal processing causes musical noise. Since such musical noise make users uncomfortable, it is desired that musical noise is mitigated. Moreover, in these days, it is reported that higher-order statistics is strongly related with the amount of generated musical noise. Thus, we analyze the integrated method of microphone array, signal processing and nonlinear signal processing, based on higher-order statistics. Also, we propose an architecture for reducing musical noise based on the analysis. The effectiveness of the proposed architecture and analysis correctness are shown via a computer simulation and a subjective evaluation. |
