扩频通信在低压电力载波通信系统中的抗干扰性分析

Anti-jamming analysis on spread spectrum communication in low-voltage power line carrier communication system

简要介绍低压电力线载波通信的发展前景和技术难点,在阐述扩频通信的基本原理的基础上,将通信理论中的直接序列扩频技术(DSSS)用于解决低压电力线通信的干扰问题,采用SC1128加之辅助外围电路,设计出低压电力线载波通信系统,并对该系统进行仿真,验证DSSS技术对干扰信号的抑制作用。

In this paper, velopment prospects and we briefly introduced the detechnical difficulties of lowvoltage power line carrier communication. Then on the basis of the basic principles of Spread Spectrum Communication, we employed DSSS of communication theory to deal with the interference problem in the low - voltage power line communication. We used SC1128 with auxiliary circuit to build a low - voltage power line communication system and emulate this system, then verify the DSSS＇ s suppression effect on the undesired signal.
