title: Simulink: Real-Time Cross Correlation
body: <p>I am working on a project, it's complicated to explain fully but it goes as follows:</p>
  
  <p>We have 2 signals A and B, where B is a time delayed echo of A. I want to use Real-Time Cross Correlation to show that the time delay will remain constant while the medium through which the signals are travelling does not change.</p>
  
  <p>Issues arise due to my lack of experience with both Simulink and Communications Statistics etc..</p>
  
  <p>So how do I go about this? I have two continuous signals A and B, and I believe what I have to do is convert them to discrete signals and then use frame based processing and XCORR... but I just don't know how to go about that.</p>
  
  <p>Can anyone help? Or even provide an example of how to cross correlate two continuous signals/an example on how to use XCORR and frame based processing?</p>
