According to the basic principle of OFDM wireless communication system, a simplified mathematical model of OFDM wireless communication system is deduced. The core technology of this system is the modulation and demodulation technology based on inverse discrete Fourier transform and discrete Fourier transform. In the Matlab environment, The simulation of OFDM wireless communication system based on discrete Fourier transform verifies that the system has a good capability of resisting wireless channel interference. A fast algorithm and its hardware implementation of OFDM wireless modem system are proposed.
