Description: OFDM is a new technology developed in recent years, high-speed wireless data transmission in the field of great applications. This paper analyzes and summarizes the basis of relevant literature, describes orthogonal frequency division multiplexing (OFDM) technology, history, orthogonal frequency division multiplexing discussed the basic principles and implementation methods. The analysis shows that in the high-speed wireless communication in OFDM symbol for the elimination of interference (ISI), and so reduce the complexity of the system has great advantages. Orthogonal frequency division multiplexing (OFDM) is a multi-carrier wideband digital modulation techniques, can effectively overcome the transmission of multi-path interference and the elimination of intersymbol interference, the ground for high-speed video transmission channel. In this paper, OFDM technology, a more detailed analysis, and transmission characteristics of OFDM FFT algorithm based on the MATLAB software simulation
