基于DSP的OFDM高速电力线载波通信系统

The Design of OFDM for High-Speed Power-Line Communication Based on DSP

多载波频分复用(OFDM)技术具有抗干扰能力强、带宽利用率高、结构简单、成本低等优点,文中结合电力线信道的特点,介绍了基于OFDM技术的电力线载波通信系统设计,探讨了以DSP为核心的调制解调部分的系统实现并给出相关参数,简单地说明了OFDM技术应用于电力线高速数据传输的可行性。

The OFDM technology has the advantages of strong anti-interference ability, high bandwidth utilization, simple structure and low cost. The paper analyzes the characters of power-line channel, and then designs a high speed com- munication system based on OFDM technology. The implementation of OFDM modulation based on DSP is discussed and relevant parameters are given. Then the feasibility of OFDM technology applied in power-line communication is verified.
