【摘要】Utilizing the wide band performance of terahertz spectrum has attracted great attention in developing wireless communication system beyond Gbps. This paper describes a 0.14 THz band wireless communication system witli I0Gbps tranqmission data rate. This system is hased on super-heterodyne structure. IF signal is processed with digital 16QAM modulation, which is converted to RF frequency with Schottky diode sub-harmonic mixer. Working in 133.8 CHz-I37.4 CHz band(BW=3.6 CHz), 10 Gbps wireless signal transmission has been achieved successfully over a distance of 500 m with output power of O dBm, and transmission error bit rate less than 10-6.%太赫兹通信由于其固有的宽带特性,在Gbps以上的高速无线通信领域受到广泛关注.本文描述了一种工作在0.14 THz频段的无线通信系统,传输速率达10 Gbps.该系统基于超外差结构,中频采用数字信号处理技术进行16QAM高阶数字信号调制解调,依靠肖特基二极管次谐波混频技术实现从中频到太赫兹信号的频谱搬移.目前该系统已经通过了500 m 10 Ghps距离无线传输实验验证,通信频段为133.8 GHz~137.4 GHz,带宽3.6 GHz,发射功率0 dBm,传输误码率低于10-6. 【总页数】5页(265-269)
