Abstract

This paper presents a prototype of the COFDM demodulator conforming to the European DVB-T standard. The proposed prototype mainly contains four blocks: time synchronization, frequency synchronization, 2K/8K FFT processor, and channel estimation. Each block is implemented by the relatively simple algorithm to avoid the overhead of hardware complexity. TSMC 0.18 mum CMOS technology is adopted to carry out the proposed COFDM demodulator. The proposed prototype uses 637 Kbits of SRAM and occupies a total area of 17.2 mm²
