CHAOGAOSI
研究表明超高斯分布更加贴近语音信号的实际分布,然而语音信号很难用单一的概率密度
函数准确描述,针对这一情况,提出了一种用超高斯混合模型对语音信号幅度谱建模的新方法,并推导了
基于此模型的幅度谱最小均方误差估的估计式。仿真结果表明:与传统的短时谱估计算法相比,该算法不
仅能够进一步提高增强语音的信噪比,而且可以有效减小增强语音的失真度,提高增强语音的主观感知
质量。 (Recent research indicates that the speech spectral amplitude distributions could
be fairly described with super-Gaussian probability density function. However, the complexity
of speech signal determines that the distribution statistics ofspeech signal could not be well
described by single simple function. Thus a super-Gaussian mixture model for speech spectral
amplitude is proposed, and with this model, a minimum mean-square error (MMSE) estimator for speech
signals spectral amplitude is derived. The simulation results show that this algorithm based on
Gaussian and super-Gaussian speech model could achieve better noise suppression and lower speech
distortion as compared with the conventional short-time spectral amplitude estimation algorithm. )

用Argo的netCDF文件计算海洋混合层和障碍层深度并通过M_Map工具包画出全球海洋MLD和BL的分布图。
P.S.: 1.需先安装m_map的toolbox。2.混合层及障碍层的定义参考Clément de Boyer Montegut, et al. "Mixed layer depth over the global ocean: An examination of profile data and a profile‐based climatology." Journal of Geophysical Research: Oceans 109(2004).(Use netCDF file to calculate the mixed layer and barrier layer and draw the global distribution figures with m map in matlab
1Please install m_map toolbox first 2The definitions of mixed layer and barrier layer used is provided by Montegut, et al 2004: Mixed layer depth over the global ocean: An examination of profile data and a profile based climatology.)
