PREDICTIVE SCHEMES FOR FUTURE POWER LINE COMMUNICATION Part Two PLC Channel Analysis and Model

为了设计基于电力线通信 ( PLC)的高速可靠通信系统 ,必须了解衰耗、阻抗、噪声等电力线信道特性。文中在实验基础上研究了信道的各方面特性 ,阐述了基于 PLC设计的先决条件 ,建立了反映信道传输主要特性的模型 ,估算了信道容量 。

The design of reliable high speed communication systems for power line communication (PLC) requires an accurate knowledge of such channel specific characteristics as attenuation, impedance and noise. On the basis of experiments, the channel characteristics are studied. The preconditions for system design based on PLC are described and channel models are developed for reflecting the main characteristics of typical transfer functions to evaluate the capacity of channels. The schemes for noise handling and channel reconstructing are discussed.
