Gain predicition in G729

Started by adithya rao k October 8, 2003

In the G 729 encoder part the gain prediction block(3.9.1 in ITU document)
is confusing. I was not able to find the way to calculate the fixed codebook
gain and the gamma value. I am not able to find the flow of the calculating the
fixed codebook gain. I don't know either first to compute mean removed
energy(Em) or MA predicition. It is somewhat cycle type in which there is
dependeancy of some other value which is not computed. Please can any one help
me sorting out this.
