coherence_MVDR_jacob-benesty
本文介绍MVDR算法实现及其改进 用于多麦克风语音增强(The minimum variance distortionless response (MVDR),
originally developed by Capon for frequency-wavenumber
analysis, is a very well established method in array process-ing. It is also used in spectral estimation. The aim of this
paper is to show how the MVDR method can be used to es-timate the magnitude squared coherence (MSC) function,
which is very useful in so many applications but so few
methods exist to estimate it)

chirplet_analasis
针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点,文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数,得到其能量分布集中于信号的调频率曲线上的结论,此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计;然后通过解线性调频技术获得其初始频率和宽度的估计,仿真结果验证了本文算法的有效性。(this code includs one method for chirplet analasis,that is used in voice and ultra-wave analasys,etc.)

熵值越大则每个符号包含的平均信息量越大。有研究发现,在有噪声的语音信号中,语音信号的熵和噪声信号的熵存在着较大的差异,对噪声信号来说在整个频带内分布相对平坦,熵值小,语音信号集中在某些特定频段内,熵值大。因此利用这个差异可以区分噪音段和语音段。(The greater the entropy is, the greater the average information of each symbol is. It is found that, in noisy speech signals, the entropy of speech signals and the entropy of noise signals are quite different. For noisy signals, the distribution is relatively flat in the whole frequency band, and the entropy value is small. The speech signal is concentrated in some specific frequency bands, and the entropy value is large. So the difference can be used to distinguish the noise segment and the speech segment.)
