Research output: Contribution to journalJournal Article peer-review


We propose a PC-based real-time software Digital Video Broadcasting- Terrestrial (DVB-T) receiver, including hardware, driver, and software parts. The total data rate of DVB-T is much greater than that of Digital Audio Broadcasting (DAB). A more efficient signal processing algorithm than our previous software DAB receiver is necessary to improve the speed of the software part of the DVB-T receiver. Therefore, we propose some modifications in software: Viterbi algorithm optimization, and Digital-Down-Converter (DDC) optimization. Finally, it only takes 1541 ms to decode the 2760ms video data in this system, and the data recoded at 100km/hr vehicle speed is successfully decoded.
