For the design of inter-satellite Terahertz communication transmission system, the overall designs of links, such as encoding of LDPC code, direct modulator, transmission components and antenna design, are discussed, and then the key technologies, such as time sequence adjustment of LDPC code,broadband quadrature modulation and adjustment of antenna azimuth and elevation angles,are analyzed. Finally a preliminary design scheme of inter-satellite Terahertz data eommunication transmission system is proposed, which provides technology reference for Terahertz technology applications in the field of inter-satellite data communication.
