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。文章介绍了宽带电力线通信技术,在分析电力线特性的基础上,选择了OFDM作为宽带电力线通信中的调制技术,并阐述了OFDM的基本原理,给出了用数字信号处理芯片TMS320VC5402实现基于OFDM的电力线调制解调器的软硬件结构,并设定了调制解调器的参数。
The power line has become a medium for communication. It can transmit high speed data so long as there are power lines. This paper introduces the technology of broad band power line communication, chooses OFDM as modulation technology in the broad band power line communication on the basis of analyzing the trait of the power line, and presents the basic principle of OFDM. It also proposes the software and hardware structure of power line modem based on OFDM with digital signal processing chip TMS320VC5402 and the parameter of modem.
