摘要: 设计了工作在太赫兹频段的无线通信系统,基带部分采用16QAM调制体制,射频部分采用混频器实现两级上下变频,功放部分采用固态功率放大+电真空器件放大级联的功率放大技术,实现了0.14 THz频段W量级的功率输出。接收端采用全固态常温接收技术,接收机等效噪声温度为1100 K,接收灵敏度达到-57 dBm。采用两个增益50 dBi的卡塞格伦天线,在成都市双流区与新津县之间开展了距离21 km的无线通信试验,单路实时通信速率达到5 Gbps,误码率低于10-6。并成功同时实时传输了两路符合HD-SDI标准的无压缩高清视频数据流,每一路的标准有效速率达到1.485 Gbps。Abstract: A terahertz wireless communication system is designed. The 16QAM modulation scheme is used in baseband processing, and mixers are used for cascading frequency up and down-converting. Cascading power amplification technique is adopted with a solid-state power amplifier and a vacuum electronic device. Several watts power is emitted at 0.14 THz. An all solid-state receiver running in room temperature is used, whose equivalent noise temperature is 1100 K and receiving sensitivity is -57 dBm. A 21 km wireless communication testing is carried out between the Shuangliu district and the Xinjin county of Chengdu, by means of two Cassegrain antennas with 50 dBi gain each. A 5 Gbps single-channel transmission speed is measured with bit error rate below 10-6. For testing, two standard HD-SDI uncompressed video streams are successfully transmitted in real time simultaneously, with an effective speed of 1.485 Gbps for each one.
