Digital Terrestrial Transmission System and Its Covering——2017 RIIT Academic Salon 2
On June 23, 2017 RIIT Academic Salon 2 was held at noon. Yang Fang, the Deputy Director of Digital and TV Technology Research Center, was invited to give a lecture on “Digital Terrestrial Transmission System and Its Covering”.
At present, with the demand of domestic application and overseas promotion of DTMB, China Domestic TV Terrestrial Multimedia Broadcasting needs to solve the problem of transmission core technology and coverage optimization. To solve the transmission and network construction problems encountered in engineering practices of terrestrial digital television, the lecture analyzed related technologies and outcomes: low density parity check Code (LDPC) based channel coding, framework of multi-layer modulation, time-frequency joint signal processing, architecture of wide area network and optimization of single frequency network.
