Abstract :
The FFT and equalizer units are core components of OFDM receivers for multicarrier reception in consumer applications. This paper presents a novel FFT architecture with adaptive scaling and a new equalizer architecture circumventing the need for explicit arithmetic division. For the example of DVB-T COFDM terrestrial digital TV reception, the tradeoff between complexity and performance is investigated under relevant reception conditions.
