Abstract:Utilizing the wide band characteristic of Terahertz spectrum is an important research aspect of high data rate information transmission.Low radiation power,high atmosphere attenuation and lack of efficient modulation/demodulation methods are important limiting factors of THz communication.This paper proposes to realize THz communication based on Schottky diode subharmonic mixer + high data rate 16 QAM digital modulation/demodulation scheme with the advantage of improving the spectrum efficiency.A 140 GHz wi...
Keywords:Wireless communication  Terahertz  High data rate information transmission  Schottky diode mixer  High speed digital modulation/demodulation technology
