Spread Spectrum Technology In The Low-voltage Power Line Data Transmission Applications

This paper integrated with project studies the subject of data transmission using spread spectrum technology on low-voltage power line in distribution automation. First, a type of abstract channel model is concluded by analyzing the low-voltage power line channel character. Then, an optimal spread spectrum communication scheme that is suited for low梫oltage power line channel is put forth on the basis of introducing the basic mode of the spread spectrum communication, and a part of analyzing and circuit design is done for its concrete implement. At last, the system performance is analyzed from the whole system structure.
