A power-efficient single-chip OFDM demodulator and channel decoder for multimedia broadcasting

Orthogonal frequency division multiplex (OFDM) modulation makes possible heterogenous broadcasting networks in which satellites and terrestrial transmitters share the same frequency. A single-chip channel demodulator and decoder IC (DABchic) for consumer receiver products is based on the new digital audio broadcasting (DAB) standard. The challenging aspects in the design are: level of integration, silicon cost, design time, and power dissipation.
