Research and Implementation of Powerline Communication Channel Based on OFDM

摘要: 作为一种新兴的通信方式, 电力线通信已经逐渐进入人们的生活.为了实现更强的可靠性和更高的数据速率, 分析电力线的信道特性已成为电力线通信芯片设计中不可忽略的一环.在分析噪声与衰减等传统信道特性的基础上增加了载波频偏这一新的特性, 完成了整个信道的RTL级仿真和FPGA验证, 并给出了DC综合结果.

Abstract: As an emerging way of communication, in recent years, power line communication has gradually entered people's life. In order to implement better reliability and higher data rate, analyzing the features of power line channel has already played an important role in the design of power line communication chip. Based on the analysis of traditional channel characteristics such as noise and attenuation, carrier frequency offset as a new feature is appended in this paper. The RTL simulation of the whole channel is completed, and the results of DC synthesis are finally gotten.
