摘要
本文针对低压电力线分析归纳了信道的阻抗、衰减和噪声三大传输特性,并以此为基础建立了简化的电力线信道模型。利用计算机软件搭建仿真平台,对常见的DSSS、FSK和BPSK三种调制技术做了抗干扰对比仿真实验,仿真结果表明低压电力线通信系统比较适合采用DSSS和BPSK这两种调制技术。
This paper analyzes the impedance, attenuation and noise characteristics of low power line channel. According to the characteristics, the paper has given a simplified channel model, and has done the anti-jamming simulation experiment for DSSS, FSK and BPSK modulation technology on the computer and software platform. According to the result of experiment, both DSSS and BPSK were appropriate for the low voltage power line carrier communication system.
