扩频技术在电力通信中的应用

The Application of Spread Spectrum In Power Line Communication

阐述了扩展频谱技术的基本原理和特点,并设计了实际电力线直扩载波系统方案。基于直接序列扩频技术的电力线通信具有良好的抗干扰性和保密性,通过实验和证明该方案是可行有效的。

This paper mainly discussed the theory of Direct Sequence Spread Spectrum(DSSS), and designed a practical scheme for the power line DSSS carrier communication system. After the experiment and analysis,it is showed that the DSSS technique in power line communication had the characters of better interference rejection and security, so it is feasible and effective.
