【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。更多还原

【Abstract】 After the lowvoltage 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,narrowband interference and impulse noise are presented in the approximate function models.更多还原
