摘要
Abstract
A high speed terahertz wireless communication system based on the combination of carrier suppressive mixer and bias power of the carrier is proposed.In the transmitter,the On-Off Keying(OOK) modulation at 140 GHz is utilized by the combination of carrier suppressive sub-harmonic mixer and bias power of the carrier.An envelope detector is used to detect the signal in the receiver.The detector response experiments under three conditions,which are different local oscillator power and bias power,different base band signal power and bias power,different input signal power,are all carried out.Experiment results will have a guiding significance on the design of OOK modulator,and the optimization of the OOK based communication system.Finally,with the optimized system parameters,the 140 GHz wireless link succeeds in data transmission of 16 Gbps data over 70 cm with Bit Error Rate(BER) less than 10-5.关键词
