Abstract :
A 0.14THz point to point communication system based on all solid-state electronic devices has been developed. The carrier frequency is 140.3GHz with output power of -1dBm. 16 QAM modulation has been applied in signal processing to achieve 2.75 bit/Hz spectrum efficiency. It has successfully transmitted 10Gbit/s data over 1.5km with bit error rate (BER)<;1e-6 based on non-realtime software demodulation. 2Gbit/s data transmission has also been realized over 1.5km with BER=1.7e-7 based on realtime hardware demodulation.
