| Abstract(in English) | This paper proposes a new microphone array system which estimate impulse responce between two microphones. By estimating impulse responce, it can improve output signal to noise ratio. Conventional estimating methods such as NLMS (Normalized Least Mean Square) behaves as linear prediction filter in microphone array system. Therefore, it disturbs estimating impulse response in this case. In this paper, we employ EE' algorithm to estimate impulse response between two microphones. Simulation results show that the proposed system can filter out noise signal from input signal effectively. |
