hi,
i am trying to implement nlms algorithm and i am writing in c.
I am having problem with the update of the coefficients. Is the equation i have
written to update weights correct??
part of my code:
 for (i = 0; i < WLENGTH; i++)
 {
   xsquare += dly_adapt[i]*dly_adapt[i];
 }
for (i = WLENGTH-1; i >= 0; i--)         
  {
   w[i] = w[i]+(beta*E*dly_adapt[i])/xsquare;  //update weights of adaptive FIR 

   dly_adapt[i+1] = dly_adapt[i];      //update samples of adaptive FIR   
  } 

And now, how can i modify the weights equation if i am using fxnlms?
