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

In this paper,we briefly introduced the development prospects and technical difficulties of low-voltage 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.
