Triple-Network Convergence of Power Lines as a Transmission

Chen Wu Li, Jian Zhang, Qin Xie

Abstract

By analyzing the transmission characteristics of power line and the orthogonal frequency division multiplexing (OFDM) communication system, the concrete scheme of triple-network convergence based on the transmission medium of power line was given out. The Methods of constructing the intelligent triple-network convergence based on the OFDM technology, the system model and the hardware realization methods of power line communication system based on the DSP chip were given. Combining the latest OFDM technology, the channel coding technology and the modulation and demodulation technology in the power line communication system were researched, and new technology to high-speed data transmission on the radio channel was achived. And the simulation results of system design was given.
