摘要
低压电力线信道特性较为复杂,对载波通讯信道质量有较大影响,应按照测量数据对500k Hz至30MHz频段状态下,低压电力线载波通信信道所具备的阻抗特性、衰减特性以及噪声特性实施分析,以便对低压电力线信道特性有更为全面的了解。本文从阻抗特性、噪声特性等多个方面分析了低压力线载波通信信道的特性,同时简要介绍了如何进行低压电力线通信信道建模工作,以期正确分析低压电力线载波通信信道。
the low-voltage power line channel properties is more complex,on the quality of carrier communication channel has greater impact,should follow the measurement data of 500 KHz to 30 MHz band state,low-voltage power line carrier communication channel has the characteristics of the impedance,attenuation characteristics and noise characteristics analysis of the implementation to the characteristics of the low-voltage power line channel has a more comprehensive understanding.The from the multiple aspects of the impedance characteristics,noise characteristics analysis the characteristics of low pressure line carrier communication channel,and briefly introduces the modeling work in low voltage power line communication channel,in order to correct analysis of low voltage power line carrier communication channel.
