CELP ACELP & RCELP is all based on LPC.LPC means Linear Predictive Coding;CELP
means
code exited Linear Predition ;RELP means Residual Excited Linear
Prediction;ACELP
means Algebraic Code Excited Linear Prediction,which is a simple version of
CELP. You
can get the detailed imformation by using Google searching engine. B James <> wrote:

Hi,
What is diff between CELP ACELP & RCELP?
What is meaning of zero excitation to synthesis filter in case of
CELP,
will the output not be zero corresponding to zero excitation
since filter is a linear system)?

thanx in advance,
Mahesh
