Recursive blind equalizer based on Godard's criterion for FM broadcasting
Dominique Nussbaum, Pascal Scomazzon · 2002
This paper presents a new recursive structure based on Godard's criterion for blind equalization. The effectiveness of the new equalizer, called "full feedback constant modulus algorithm" (FF-CMA), is studied for conventional FM broadcasting. The FF-CMA is compared to that of its transversal counterpart, the classical constant modulus algorithm (CMA), and the results indicate that the FF-CMA exhibits superior performance in the case of multipath propagation. In the presence of interference, the FF-CMA performs slightly better than the CMA.
