The Communication Circuit of Carrier Wave in Low Voltage Power Line based on Software

摘要

Because the character of the low voltage power line chanel of communication is scurviness, a kind of circuit for communication, which use the software to modulate and de modulate based on the hardware of the fast CPU. This system adopt narrow band spreadspectrumcom communication based on double-frequency carrier wave, it both have the advantage of the narrow band communication and broadband communication, moreover the intergration of the system is high, and the cost is cheap.
