I am trying to solve this question but I am confused on some aspects

  1. When solving part B what power signal will we use. Will we use power signal before repeater 2 or after repeater 2 (x5)

  2. When finding maximum bit rate what should the SNR value? should it be average of all the SNR or what?

  • $\begingroup$ This is not a homework this is a practice question which might come with changed values in our exam. $\endgroup$

  • $\begingroup$ I know this isn't mentioned above, but you need to make sure that you know whether these are amplify and forward or decode and forward repeaters; that makes a lot of difference for the calculation! $\endgroup$ Oct 17 '16 at 9:03
