Multi-Speakers Direction-Of-Arrival Finding using ICA
Mahmoud Atashbar, Mohammad Hossein Kahaei · 2006
Multi-speakers direction finding and localization play important roles in a variety of applications. In this paper, a new quantitative measure of separation ratio is defined and then the independent component analysis (ICA) is used to detect signal frequencies of different speakers. We then apply the single source direction finding technique to each separated signal. Using this technique, we expect to obtain a higher angular resolution for more than two speakers
