Hi there,

"estimation, pour chacune des sous-bandes du module carré │X ̂k,l,i│2 d'une composante débruitée de sous-bande X ̂k,l,i propre à chaque sous-bande d'un signal débruité X ̂k,l par un algorithme de soustraction spectrale multi-bandes dit "SSMB" à partir des modules carrés de sous-bande │X ̂k,l,i│2 et des composantes de bruit de sous-bande ..;

sub-band square moduli?

Thank you for your time
Proposed translations (English)
3 +3 modulus squared of each subband

@Terry The reason is simply that multiplication of a complex number (as signals are often represented) by its complex conjugate produces the mod squared automatically, so there is no point adding an extra step by taking the square root.
Terry Richards Apr 1, 2014:
A question... I'm sure you are right but why take the modulus when you are going to square it anyway? -2 squared is the same as 2 squared...
chris collister Mar 31, 2014:
Note that the "modulus squared" is indicated in your text by the characters│X ̂k,l,i│2, where the uprights indicate the modulus (or absolute magnitude), eg |x| for "mod (x), and the 2 should be a superscript. I have no idea as to the significance of the k, l, i which may (or may not) be subscripts.

modulus squared of each subband

SSMB = self-similar block matching. I'd probably pluaralize the subbands rather than the modulus.

Thanks Chris. It looks like the freq sampling is indexed by "k", the time frames by "l" and the sub-bands by "i".
