Abstract :
All-digital automatic frequency control (AFC) for consumer applications must be both reasonably simple and effective in all kinds of environments. This paper presents the AFC synchronization strategy and algorithms implemented in a DVB-T compliant single-chip CMOS device for COFDM terrestrial digital TV reception previously developed by Fechtel, Schollhorn, Speth, Fock and Schotten (see ibid. vol.44, no.3, p.1012-18, 1998) and gives results on AFC performance in both stationary and mobile environments
