WebMicrophone array systems have been widely used in speech and au-dio applications to extract signals of interest from noisy observa-tions in room acoustic environments [1–11]. … WebSep 7, 2007 · A new DOA estimation method using a circular microphone array Abstract: This paper proposes a new DOA (direction of arrival) estimation method based on circular microphone array. For an arbitrary number of microphones, it is analytically shown that DOA estimation reduces to an efficient non-linear optimization problem.
