The design on the system of low-voltage power line carrier-current communication based on OFDM was finished in this paper. Then model of the system was simulated and the modulation and demodulation of OFDM were realized. The results show that the integral performance can be enhanced with channel code. And the bit error ratio (BER) of the system is different with several sub-carrier wave modulation modes. This system could satisfy the requirement of power line communication basically.
