Feasibility and Requirement Analysis of Terahertz Space Communication
Song Li · Journal of Dalian University · 2015
Terahertz(THz) communication has a broadly applied prospect in the future space communication field with high speed. At present, most THz communication researches focus on devices breakthroughs and building ground short-range communication system. Feasibility and requirement analysis of THz space communication have not been carried out. In this paper, the progress in THz communication technology over the past few years is reviewed, considering THz device development level, the feasibility and requirement of THz space communication is analyzed. It is concluded that, satellite layer communications can be achieved in all THz band. But communication frequency of the electron emission system and the photoelectron emission system should be respectively more than 7.43 THz and 27.8TH when communicate between multilayer. For the photoelectron emission system is influenced by the background light, it is better to adopt the electron emission system in multilayer communication.
