| Abstract: | According to the synchronization requirements of Single Frequency Network(SFN) in national Digital Terrestrial Television Broadcasting(DTTB) standards,an adaptor is designed in this paper.The GPS receiver is used to provide precise 1 PPS(Pulse Per Sec-ond) pluse and 10 MHz synchronizing clock to the SFN adaptor,and the Second-frame Initialization Packet(SIP) and code rate adaptive processing to the input TS are carried on,in order to realize the time synchronism and the symbol synchronization requirements. |
