Similar to the definition of sm, i, the decomposed short-term distortion frames εm, i can also be represented as εm, i = ε m ∗ g i.
The Wigner distribution is one such kernel, but is extremely susceptible to cross-term distortion [19], and when signal characteristics are unknown, this distribution becomes difficult to interpret.
The distortion signal ε (n) is then recorded by a microphone, and TF decomposition and GT filtering are once again performed to obtain the short-term distortion frame ε m,i.
The tap length of NLMS is short because the goal of this filter is to eliminate a short-term distortion, whereas the proposed dereverberation algorithm (3.2) attempts to eliminate late reverberation.
This section deals with speech enhancement methods: delay-and-sum BF with cross-spectrum phase (CSP) analysis in Section 3.1, a proposed dereverberation method in Section 3.2, and an NLMS algorithm that attempts to eliminate short-term distortion in Section 3.3.
Population losses and movements on this scale introduced long-term distortions into demographic structures and trends.
And he frets over long-term distortions, including the financial sector expectations that they'll be bailed out by low interest rates whenever they get into trouble.
"The collective impact of this behavior risks either causing inflation and asset bubbles in emerging economies, or else depressing consumption growth and intensifying short-term distortions in favor of exports".
At any rate, it is not the Fed's job to guarantee a predictable return for owners of financial assets; it's mandate is price stability and full employment.Mr Rajan worries about the short-term distortions from a low interest rate policy, including bubble creation and over-leveraging, but there isn't the least sign of either in the economy at present.
Exceptions can occur, however, due to meiotic drive, competition among gametes, or viability selection, which we collectively term "transmission distortion" (TD).
In the longer term the distortions caused by such measures become more burdensome.
