CELP IN SIMULINK - neeta chapatwala - Feb 20 8:16:02 2008



Hello,
  I am doing M.Tech. project on CELP in real time using DSP kit TMS320c6713
  Note that I had refer CELP demo given in simulink.
   
  I am using simple gaussian codebook ,LPC parameters(LPC co-efficients and reflection 
co-efficients).
  My problem is how to find index for codebook?
  what will be gain for excitation signal coming from codebook?This gain will be constant or
variable per frame?
  please help if any one can do.
  Thanks
