Abstract :
In this paper, realization of high speed carrier communication module using new coded orthogonal frequency division multiplexing (COFDM) is discussed. OFDM theory and its coding technology are simply introduced .The advantage of using COFDM modulating technology in power carrier wave communication is analyzed, and data transfer flow of the corresponding COFDM wave-carrier system is presented. The module design based on DSP is put forward, channel coding simulation and hardware composition and realization are also presented in this paper.
