   I wasn't gonna comment any more but there is this question:   
      
   For a matched filter you start with a replica of the signal of interest.   
   You use this to operate on a noisy/perturbed version of the signal.   
   Then you operate some more.   
   Then you operate some more....   
      
   And, in the end you get the replica which you started with????   
      
   How is that useful?  You already have the replica.  That's what you   
   started with.  Extracting the replica from itself seems useless.
