| 摘 要： | 复杂的噪声干扰是阻碍电力线通信技术发展的主要原因之一，准确的噪声仿真对电力线通信的进一步发展具有重要意义。搭建噪声测量电路，对信道噪声进行了测量。通过对实测信道噪声进行傅里叶变换和时频分析，得到了3类信道噪声的正弦波成分，最终以不同频率的正弦波叠加形式仿真合成了3类PLC信道噪声。实验结果表明，仿真得到的信道噪声与测量所得到的信道噪声具有很高的一致性。

| Abstract: | Complex noise is one of the main reasons for hindering the development of power line communication technology. Accurate noise simulation is important for the further development of power line communication. The noise measurement circuit is built and the channel noise is measured in this paper. The measured channel noise is analyzed with Fourier transform and time-frequency analysis, and the sine components of three channel noises are obtained. Finally, three PLC channel noises are simulated by superposing different frequency sine waves. The experimental results show that the simulated channel noise and the measured channel noise have high consistency. |
