There are too many blocks to understand in it and I am getting lost in the explanation.
Specifically I want to know How and Why the medium time power calculation is used to motify the short-time power calculation.
It says in the paper (page 7, left column, bottom) that
The time-averaged, frequency-averaged transfer functionS˜[m, l] is used to modulate the original short-time power P[m, l]
I don't understand why do they use the term modulation. I thought they were going to subtract the noise power from speech signal power, why are the multiplying the two?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I am reading the latest (2016) PNCC paper. https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7439789
