| 目的 针对矢量毫米波系统中因传输链路和光电转换带来的非线性问题，提出一个基于维特拉级数的非线性均衡方案。方法 首先给出该方案的基本原理，然后搭建一个射频载波频率为40 GHz、传输信号为5 Gbaud 16QAM的矢量毫米波仿真系统，分析基于维特拉级数的非线性模型各阶非线性项的贡献，并比较在不同传输距离情况下，该方案相对于仅采用线性均衡方案对系统性能的提升。结果 在传输距离为10 km时，该方案能够将平台误码率降低到10?3以下。结论 该方案明显提升了系统的性能。 |

| Objective To propose a nonlinear equalization method based on the Volterra series to solve the nonlinear problems caused by transmission link and photoelectric conversion in vector millimeter wave system. Methods Firstly, the basic principle of this method was given, and then a vector millimeter wave simulation system was built. Its RF carrier frequency was 40GHz and its transmission signal was 5Gbaud 16QAM. Finally the nonlinear term contribution of the nonlinear model based on Volterra series was analyzed. The nonlinear equilibrium method′s ability to improvement of the system performance was compared with the linear equilibrium scheme in the case of different transmission distance. Results When the transmission distance was 10km, the proposed nonlinear equalization method could reduce platform bit error rate to less than 10?3. Conclusion This plan significantly improves the performance of the system. |
