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

摘要

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.
