摘要
电力线用来作为通信媒介已成为现实,只要铺设电力线的地方,就可以进行高速数据传输。用电力线上网是通信技术发展的趋势,也是通信技术多样化,现代化的要求。本文介绍了宽带电力线通信的国内外研究的历史及现状,研究了宽带电力线通信关键技术,对其中OFDM技术高峰值平均功率比算法进行了仿真分析,重点研究了宽带电力线通信自适应均衡各种算法,并对主要算法进行了仿真,给出了自适应均衡的软件实现方案。设计出基于DSP的宽带电力线调制解调器整体方案,建立了宽带电力线调制解调器的系统硬件结构和系统实现流程,进行了参数设计,最后指出了一些设计调试过程中需注意的问题。
The power line has become a medium for communications, which can transmit high speed data so long as there are power lines. To connect internet by power line is a trend of communication technology, it is also the demand of diversity and modernization. The history and current situation of study on broadband PLC at home and abroad are presented in this paper, the key technology of broadband PLC is reaserched, Peak-to-Average Power Ratio of OFDM is simulated with MATLAB, the algorithms of adaptive equalization are mainly researched, main algorithms are simulated, and software realization scheme of adaptive equalization is presented. The whole scheme of broadband power line modem based on DSP is planed, the hardware structure and the implement steps of the broadband power line modem system are established, the parameters are designed, and some debugging problems are pointed out at the end of this paper.
