摘要

提出了一种基于相干函数的移动通信双传声器降噪方法。该算法利用卡尔曼滤波和频谱减法来提高不同噪声环境下的语音质量。该方法实现简单，不需要估计干扰信号的统计量。利用记录数据和客观标准(如PESQ和SNR)对该算法进行了测试。该算法具有良好的性能和较低的复杂度，使其成为双通道手机的理想解决方案。

A dual-microphone noise reduction algorithm for mobile communications

A dual-microphone noise reduction method based on the coherence function for mobile communications is suggested in this paper. The proposed algorithm exploits the Kalman filter and the spectral subtraction method in order to improve the speech quality in different noisy environments. The adopted method is easy to implement and needs no estimation of interfering signals statistics. The proposed algorithm is tested with different distances between the two microphones using recorded data and objective criteria such as: PESQ and SNR. The good performance of the suggested algorithm and its low complexity, making it a promised solution for dual-channel mobile phones.
