Spectral-subtraction
学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)

MAP,MLE
MAP最大后验估计，用于图像去噪方面尤其是MR图像低噪声水平时(it was demonstrated that the MAP estimator provides less biased estimation of OCT signal amplitude and intensity. It also provides higher contrast images at the vitreous and choroid than standard signal intensity averaging and can enhance the clinical utility of OCT. The quantitative estimation of MAP can be used as preprocessing for further analysis of OCT. In particular, OCT intensity images obtained by MAP estimation can enhance the ability of other quantitative signal evaluation methods, such as attenuation coefficient imaging. This will finally enable more accurate diagnosis of pathologies.)

The model used for creating the reference voltage is shown
in Fig. 4. First, photovoltaic output current (Ipv) and output
voltage (Vpv) are passed through a first order low pass filter
with a magnitude of G = 1 and a time constant of T = 0.01
seconds in order to filter out the high frequency components
or harmonics from these signals as shown in Fig. 5 and Fig. 6.
The filtered current and voltage signals (Ipv_F and Vpv_F) are
then fed into the MPPT control block that uses the Incremental
Conductance Tracking Algorithm. An algorithm that is based
on the fact the slope of the PV array power curve shown in
Fig. 7 is zero at the Maximum Power Point (MPP), positive on
the left of the MPP, and negative on the right. The MPP can
thus be tracked by comparing the instantaneous conductance
(I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
