摘要
在对低压PLC信道噪声特性进行分析、建模仿真的基础上,由MATLAB/Simulink模型直接生成DSP代码,设计并实现了一种低压电力线噪声发生器。用于模拟电力线上几类主要的噪声,将其作为电力线通信系统中独立、可控的噪声源,为电力线通信系统调制解调技术及纠错编码的研究提供可控制的实验环境。实验证明该发生器输出的噪声可满足电力线通信系统设计的需要。
The low-voltage PLC channel noise characteristics are analyzed and the mathematical models are established. DSP codes are generated directly by MATLAB/Simulink model, and then a low-voltage power line noise generator is designed. The noise generator can be used as an independent and manageable noise source for the power line communication system, to simulate the primary noises on the power line. It can provide a manageable experimental environment for researching the demodulation and the error correction codes about the power line communication system. The experiments prove the noises generated by the generator meet the needs of the power line communication system.
