hi everyone
im new here and im from vietnam and im doing my thesis on OFDM and reduce PAPR by ACE method. And I have to do the matlab code for simulating OFDM system and matlab code for reducing PAPR
But i get stuck
1. ACE is active constellation extensions, the idea behind ACE is that we can move the constellation points so that the high peak of the signal in time-domain will be canceled. But... how? I cannot imagine how can the action of extending the constellation points can cancel out high peak that cause high PAPR?
