摘要：
This paper proposes a microphone array solution for speech enhancement in hands-free communication systems. The proposed algorithm aims to enhance a target signal corrupted by background noise as well as the acoustic echo. The main idea lies in the incorporation of both the source and the interference short-term spectral amplitudes in the solution. These spectral components are estimated iteratively to provide a spectrally optimized constraint. Evaluations in a hands-free car environment show that the proposed algorithm is good in suppressing both the noise and the interference even in a double-talk situation.
