This paper describes a single chip DVB compliant receiver that integrates a variable rate QPSK demodulator with a Viterbi decoder, de-interleaver, and a Reed-Solomon decoder. Using a fixed rate sampling clock it handles continuously variable symbol rate from 1 Msps to 45 Msps. Careful floorplanning and flat place & route squeezed the 116,000 nand-cquivalcnt gatc design into an arca of 38.8mm2. It has been fabricated with a 0.5pm CMOS TLM process. It has been extensivcly tcsted in a real-world sct-up and proved fully functional. 11.7.4
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
