This paper introduces the OFDM theory and its coding technology in details. The advantage of Coded Orthogonal Frequency Division Multiplexing (COFDM) modulating technology in power carrier communication is analyzed. Using COFDM as carrier modulation technology, communication velocity becomes quicker, BER is reduced, and high reliability is achieved. Data transfer flow of the corresponding COFDM carrier system is presented. The module design based on 16-bit fixed point DSP-TMS320VC5410 is put forward and the new high-speed digital carrier communication module using COFDM technology is realized. At the same time, detailed hardware composition and realization are also presented in this paper.
