The Research and Application of the Low Voltage Power Line Carrier Communication

The present situation and development of the low voltage power line carrier communication is introduced paper after analyzing its characteristics.The technique and its advantages of modulation and demodulation of the low voltage power line carrier communication,including the common exiting power line carrier communication techniques,the frequency spectrum technique and the orthogonal frequency division multiplexing,are proposed respectively.The present situation of its application is put forward combined with the development of power line communication techniques in our country.And the present situation and its development of power line communication both home and abroad are introduced,whose future application is put forward.
