Dai, B. James- Add... MELP --> Mixed Excitation Linear Prediction -Jeff -------- Original Message -------- Subject: Re: [speechcoding] Urgent Help Needed on CELP Date: Tue, 11 May 2004 19:07:08 +0800 (CST) From: dai Guangfa <> To: B James <>, 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 |
