摘要
分析了低压电力线的通道特性,对1~30MHz频率范围内的噪声进行了分类并详细讨论其基本特性。在基于试验定量测定的基础上,对背景(有色)、窄带和脉冲三种主要的噪声给出了近似的模型函数。
After the lowvoltage power line's channel properties are analyzed, noises in the frequency range between 1~30 MHz are sorted and their properties are given in detail. Based on experimentation, the three main noises including background (colored) noise,narrowband interference and impulse noise are presented in the approximate function models.
