hi all,
G.729 recommendation states:-to predict the values of LSF a 4th oreder MA is
used.Two predictions are possible .the encoder chooses which one to use and
indices it with a bit in the bit stream.
after prediction ,prediction error is computed .this error is sent to decoder by
vector quantizing it.
my que is what are these two possible predictions ?
what is MA prediction?
can any body please explain VQ in simple terms.how G.729 does this..
any online reference wud be great help
thanx and regards.

Dear Raj,
I recommend two IEEE papers:
(1)Design and description of CS-ACELP: a toll quality 8 kb_s speech coder
(2)Implementation and performance of an 8-kbit/s conjugate structure CELP speech
coder
Best regards
