摘　　要：现有高阶调制技术存在上、下行峰值速率和空口速率过低现象。为了解决此问题,设计一种基于光子射频的高阶调制模型。通过分析OTTD光子移相技术、光载波调相技术、光谱处理射频技术,完成光子射频关键技术研究;在此基础上,通过MQAM高阶信号识别、基于MQAM高阶信号的调制子载波识别,完成基于光子射频高阶调制模型的搭建。模拟该模型的运行环境,对比实验结果表明,与传统方法相比,应用基于光子射频高阶调制模型后有效提升了上、下行峰值速率和空口速率。Since the existing high-order modulation technology has the phenomena of low uplink and downlink peak rate and low empty rate,a high-order modulation model based on photon radio frequency(RF)is designed.The research on the key technologies of photon RF was accomplished by analysis on OTTD photonic phase shift technology,optical carrier phase modulation technology and spectrum processing RF technology.On this basis,the high-order modulation model based on photon RF was established by means of the MQAM high-order signal recognition and modulated subcarrier recognition based on MQAM high-order signal.The operation environment of the model was simulated.The experimental results show that the high-order modulation model based on photon RF can improve the uplink and downlink peak rate,and empty rate more effectively in comparison with the traditional methods.
