| 摘 要： | 为了解决在NGN电话测试网中语音噪音较大的问题,本文在传统小波阈值去噪方法的基础上提出了一种新的基于阈值去噪的函数.采用新的阈值函数对染噪语音进行去噪,在信噪比增益和最小均方误差意义上均优于传统的硬阈值或软阈值函数.在NGN实验网中的测试表明,该方法有更好地去除噪音、保留有用信号的效果.

| Abstract: | To solve the problem of speech noise in NGN telephone network, based on traditionai waverer threshold denoising method, a new function based threshold denoising is proposed in this paper. Denoising method adopting the new threshold function can provide better SNR gains and MSE performance than hard or soft threshold function. In NGN testing network, experimental results indicate that this method has better denoising performance and can reserve useful signal. |
