Abstract :
All-digital automatic frequency control (AFC) for consumer applications must be both simple and effective in all kinds of environments. This paper presents the AFC synchronization strategy adopted for a COFDM receiver chip previously developed and gives results on the tracking performance in both stationary and mobile environments.
