摘要：
Microphone array technique are representative method for Direction OF Arrival(DOA) estimation. By using these technique, a large hard ware amount of the system is required to obtain sharp directivity characteristics. The fundamental principle of multiple sound source based on the parameter estimation method is proposed. The fundamental principle of the DOA estimation and the frequency and phase estimation technique are discussed. Finally, the effectiveness of the proposed method is confirmed by the experimental results. Experimental results obtained in noisy environments are also included.
