periodic noise meaning in English
周期性噪声
Examples
- A kind of general audio frequency periodic noise suppressor
一种通用的音频周期性噪声抑制器 - In this paper , eliminating the periodic narrowband noise with wavelet packet has been put forward . the periodic narrowband noise eliminating method has been proposed that has the optimal wavelet packet base . the instances show that this approach can eliminate the periodic noise of pd signal , and its dose not need set the external parameters
通过分析周期性干扰和局部放电信号的小波包分解特性，采用了最优小波包基来剔除周期性干扰，实例证明能够很好的剔除局部放电信号中的周期性干扰，并且不需要外部参数设定。 - The statistic of wavelet transform coefficient algorithm can solve the periodic noise , high - energy noise and some non - gauss noise simply and effectively ; bi - spectrum can acquire more information from the original signal than power - spectrum , detect more information except from range and restrain the gauss noise . short - time speech signal can be considered as stationary and with periodic non - gauss signal , so we can make use of bi - spectrum to obtain the speech character and separate the speech and noise and detect morse telegraph signal ; complex number spectrum variance algorithm is put forward based on the deeply observing speech data , it is a new algorithm , experiment show that it is simple , effective
统计算法在解决周期信号、高能噪声和高斯信号方面有独特之处,能简单有效提取以上噪声的特征;双谱能够提供比功率谱更多的有用信息,有效地检测信号幅度之外的其它信息,并能有效抑制高斯噪声,短时语音信号一般认为是平稳且有一定的周期性的非高斯信号,因而可以利用双谱来提取语音信号特性并实现信噪分离;复数谱方差算法是在对语音信号进行深入观察和分析的基础上而提出来的一种全新的语音特征提取方法,此方法简单而有效的提取了语音、噪声的特征以及检测莫尔斯信号,基于实验表明,该算法取得了很好的效果。
