Design,simulation And Hardware Implementation Of A Digital Television System: Synchronization Techniques
Ieee International Symposium On Spread Spectrum Techniques And Applications. , v. , n. , p. 208 - 212, 2006.
As described in , in 2005 the Brazilian government supported many research consortia in order to develop a Digital Television System employing advanced technologies for multimedia broadcasting. One of the proposals for the physical layer of this system was entitled Innovative Modulation for the Brazilian Digital TV System (MI-SBTVD). The MI-SBTVD Project includes high performance error-correcting codes, transmit spatial diversity and multi-carrier modulation. The objective of this article is to present the synchronization techniques that were used in the first proof-of-concept for the MI-SBTVD System. We present the simulated performance results for both the AWGN and multipath channels. Finally, we also comment on the implementation details of the synchronization scheme using Field Programmable Gate Array (FPGA) devices. © 2006 IEEE.208212Brito, J.M.C., Design, Simulation and Hardware Implementation of a Digital Television System: System Overview (2006) The 9th International Symposium on Spread Spectrum Techniques and Applications - ISSSTA-2006, , Manaus, BrazilATSC Standard A/53, ASTC Digital Television StandardDigital Video Broadcasting (DVB)Framing structure, channel coding and modulation for digital terrestrial television (2001), 300 (744), pp. V1.4.1. , European Broadcasting Union, ETSI ENInternational Telecommunication Union, Channel Coding, Frame Structure and Modulation Scheme for Terrestrial Integrated Services Digital Broadcasting (ISDB-T), ITU-R 205/11, 1999Castro, F.C.C., Castro, M.C.F., Fernandes, M.A.C., Arantes, D.S., 8-VSB Channel Coding Analysis for DTV Broadcast (2000) IEEE Transactions Consumer Eletronics, 46 (3), pp. 539-547. , AugustK.
