| Abstract(in English) | For sound direction estimation in the multisound field, microphone array system using the filter based on the wavelength constant matrix was proposed. In this study, the improvement on the estimation accuracy was examined through 1) introducing gray code in mapping the gene onto the sound direction in GA, and 2) using a microphone array having more elements than the sound count. As a result of simulation for estimation of six angles of three sounds, it was shown that the introduction of gray code gave a fairly better improvement of the estimation success rate and angle estimation accuracy. In addition, the improvement by increasing the microphone component count was also observed. |
