- 语音信号的频域处理,语音虽然是一个时变、非平稳的随机过程。但在短时间内可近似看作是平稳的。因此如果能从带噪语音的短时谱中估计出“纯净”语音的短时谱,即可达到语音增强的目的。由于噪声也是随机过程,因此这种估计只能建立在统计模型基础上。利用人耳感知对语音频谱分量的相位不敏感的特性,这类语音增强算法主要针对短时谱的幅度估计。 -voice signals in the frequency domain processing, voice is a time-varying, nonstationa

Gabor变换在模态参数辨识中的应用
- 对Gabor时频变换在模态参数辨识中的应用进行了探讨,将基于Gabor系数展开的时频滤波方法作为参数辨识的前处理手段之一,该方法对于平稳、非平稳信号都适用。根据信号在时频域内的分布特征,可以直接观测系统的频率分布情况、模态密集程度、能量聚集性、各通道响应信号所含特征量的多少等信息,从而对响应信号的特征构成进行初步判断,并通过剔除、截取等操作实现对响应信号的滤波,更有利于模态参数的辨识。
