| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A method for estimating the distance between a source and receiver using a small-size microphone array is proposed. The proposed method uses the spatial distribution pattern of virtual sources obtained by the frequency-domain independent component analysis (FDICA) as the cue for distance estimation. The virtual sources are calculated by applying FDICA to array signals with very high redundancy, for example, 60 microphone signals for a pair of sources; therefore, signal components associated with reflection signals are obtained even though they are correlated with the direct signal. Experimental evaluation using a small-size microphone array with a large number of elements confirms that the average estimation error of the proposed method is 0.33 m. The proposed method could discriminate nearer/further sources with better than $80\%$ accuracy when the power of far source is not much higher than that of near source. | |
