Abstract
In this paper, a new kind of COFDM demodulator is proposed, which is conforming to the European DVB-T standard. The proposed prototype mainly contains four blocks: time synchronization, frequency synchronization, 2 K/8 K FFT processor, and channel estimation. Each block is implemented by the relatively simple algorithm to avoid the overhead of hardware complexity.
