摘要：
In this paper, we present the system and software implementation of the Digital Video Broadcasting protocol for hand held applications (DVB-H), on the Sandbridge Technology's multithreaded digital signal processor SB3011. The I and Q base-band analog output signals from the tuner are digitized, filtered and further processed conforming to ETSI EN 302 304 V 1.1.1 (2004-06). All processing blocks including the receiver synchronization and forward error correction are executed entirely in software. At 1.5 Mbps the processor usage is less than 40% with maximum power consumption of 120mW.
