| Abstract: | The OFDM technology has the advantages of strong anti-interference ability, high bandwidth utilization, simple structure and low cost. The paper analyzes the characters of power-line channel, and then designs a high speed com- munication system based on OFDM technology. The implementation of OFDM modulation based on DSP is discussed and relevant parameters are given. Then the feasibility of OFDM technology applied in power-line communication is verified. |
