Abstract
The performance of directions of arrival(DOA) of audio or speech signals is deteriorated under lower signal-to-noise (SNR) condition. Stochastic resonance(SR)preprocessing is proposed to enhance the SNR of noisy speech signal, and the precise of DOA is improved. The output signal of SR system is the input signal of DOA estimation system by MUSIC algorithm, the experiment results show that the DOA estimation exhibits good performance even under -25dB or about.
