Abstract

We have developed a 0.14THz wireless link with 10Gbit/s data rate. Terahertz signal is generated and detected by Schottky diode superheterodyne transmitter and receiver. 16QAM high order digital modulation/demodulation has been successfully applied in IF signal processing, which works with non real time software method and could improve the spectrum efficiency and carrier noise rate (CNR). The system has successfully transmitted 10Gbit/s data rate signal over 0.5km with bit error rate (BER)<;10^-6, CNR>;35dB. The maximum transmission distance is estimated to be about 1.5km.
