【摘要】 由于语音通信设备的广泛应用和小型化要求,消除其中的噪声干扰成为重点研究内容。采用了一种双通道的语音增强算法。该方法基于一阶差分传声器阵列,并利用频域的最小均方误差自适应算法实现噪声消除。仿真结果表明,所采用的方法相对于时域自适应过程,加快了收敛速度,减小了计算量,并改善了噪声消除的效果,可更好地用于实际。更多还原

【Abstract】 As communication devices used widely and become more portable,the research of noise elimination has become more and more important.A dual-microphone speech enhancement algorithm is proposed,which is based on the FDM(First-order Differential Microphone) array,and uses the FLMS(least mean square adaptive algorithm in frequency domain) to cancel the noise.Simulations show that this method has faster convergence speed compared with the adaptive algorithm in time domain,decreases the amount of calculation,and improves the performance of noise elimination.So it can be used in practical applications more suitably.更多还原
