【摘要】 为了使短距离无线通信的数据速率达到10Gbps,利用光电结合技术以THz波段(125GHz)为载波,建立太赫兹无线通信系统。采用125GHz光学太赫兹波生成器、UTC-PD模块、HEMT模块、卡塞格林天线和高斯光学透镜天线提高通信系统的性能,通过理论分析及仿真实验研究了系统的输出功率、噪声特性、通信质量与天线的关系、数据传输特性及最大传输距离。结果表明:发射信号的载噪比能够满足无错传输的要求,125GHz波段无线通信支持OC-192和10GbE网络接口,利用光电结合技术实现10Gbps无线通信是可行的。更多还原

【Abstract】 In order to increase the short range wireless communication to 10Gbps,a Terahertz wireless communication system combing electro-optical technology with THz band(125GHz)for carrier was build,which adopted 125GHz optical THz generator,UTC-PD module,HEMT module and cassegrain antenna(CA)or Gaussian optic lens antenna(GOA)to improve system performance.It gives the researches about theoretical analysis and simulation results on output power,noisiness,relation between communication quality and antenna,data transmission feature,maximum transmission distance and so on.Experimental result shows that:the carrier to noise ratio of emission signal meets error-free transmission demand,125GHz waveband wireless communication supports OC-192 network interface and 10GbE network interface.So,it’s feasible to realize 10Gbps wireless communication using electro-optical technology.更多还原
