摘要:
      影响宽带电力线载波通信的关键因素之一是随机突发的脉冲噪声。目前的噪声研究大多停留在理论建模上,缺乏标准化的电力线噪声硬件实现方法。文中深入研究Markov-Middleton脉冲噪声模型,分析产生Markov性质的脉冲序列原理,利用System Generator和Xilinx Vivado联合仿真工具,设计出具有随机突发特性的电力线噪声生成系统,并完成该系统的硬件实现。通过对比现场可编程门阵列(FPGA)输出、Middleton Class A模型仿真与实测电力线噪声的统计特性,证明了该硬件实现方法能够生成具有随机突发性和时间相关性的脉冲噪声。通过搭建实验室环境下的电力线载波通信系统,测试不同参数下噪声对通信成功率的影响程度,对比其他的硬件实现方法,验证了所提方法的工程应用价值。
Abstract:
      The random burst impulsive noise is the key factor affecting the broadband power line carrier communication. Most of the existing noise research is stuck in theoretical modeling, and there is a lack of standardized hardware implementation methods of power line noise. This paper studies the Markov-Middleton impulsive noise model and analyzes the principle of generation of Markov pulse sequences. Combined with System Generator and Xilinx Vivado tools, a power line noise generating system with random burst characteristics is designed, and the hardware implementation of the system is completed. By comparing the statistical characteristics of filed-programmable gate array(FPGA)output, simulation of Middleton Class A model and measured power line noise, it is proved that the hardware implementation method can generate impulsive noise with random burst characteristic and time correlation. According to the establishment of power line carrier communication system in the laboratory environment, the effect of noise on the communication success rate with different parameters is tested. Compared with other hardware implementation methods, the engineering application value of the proposed method is verified.
