Orthogonal frequency division multiplexing (orthogonal frequency division multiplexing) is one of the most promising technologies in wireless communication tools. OFDM systems can be inserted through the cyclic prefix, effective to suppress the inter-symbol interference of multipath transmission bring, can also be based on accurate estimate of the channel characteristics, to reduce the influence of channel time-varying nature of the system. Moreover, the application of OFDM technology in the field of wireless communication has attracted wide attention due to its use of Fourier transform to greatly reduce the receiver complexity. As an efficient transmission technology, OFDM has become the core technology of fourth-generation mobile communication. To study OFDM system, a complete OFDM system is needed. After briefly introducing the basic principle of OFDM, this paper constructs a complete OFDM dynamic simulation system based on MATLAB.
