Research and Discussion on Design of Terahertz Space Communication System Based on Filter Bank Multicarrier Technology

Aiming at the problems of terahertz antenna transmit and receive channels, measurement system and waveform design, a terahertz communication system based on FBMC technology was designed. First, the frequency-doubled terahertz source is used as the carrier of the signal, and then the design improvement of the terahertz array antenna is discussed. Finally, a preliminary solution is briefly discussed to deal with the specific hardware implementation communication, which provides a technical reference for the application of terahertz technology in the field of space communication.
