Abstract :
Direction of arrival (DOA) estimation is one of the major task in many acoustic array signal processing applications. In this work, we show that a modified joint approximate diagonlization (MJAD) method utilizing temporal structure of the wideband color signals can outperform the conventional wideband DOA estimation method such as approximate maximum likelihood (AML) and coherent signal-subspace processing(CSSP).
