Since the naissance of the television broadcasting, the effective using and planning of spectrum has been an important research subject. With the development of digital terrestrial television technologies, reasonable frequency planning of digital terrestrial television reasonably will be helpful to carry out the Digital Terrestrial Television Broadcasting (DTTB). Besides, the national digital terrestrial television transmmison standard of our country has been released, the frequency planning of digital terrestrial television is put on the calendar.This paper firstly introduced the channel characteristics of terrestrial television broadcasting and three international stanndards and our national standard of DTTB. In succession, described three main technologies related to the frequency planning of digital terrestrial television: planning parameter, electric wave propagation model and planning method of coverage network. Then summarized the characteristic of RRC-06 planning of the Interational Telecom Union (ITU), and analyzed the cases of the frequency planning of digital terrestrial television in USA, Japan, Britain, and Australia. Finally, this article proposed the method for our country's frequency planning of digital terrestrial television during the period from analog terrestrial television to digital terrestrial television. Simulation was implemented by related planning tools and theories were explained when discussing.At the end of this paper, we summarized the work that had been completed and made some advices for the future work.
