Orthogonal Frequency Division Multiplexing (OFDM) has become one of the most important modulation methods in many fields, such as high-speed communication systems. It is proposed that OFDM technique can offer variable bandwidth, improved protection to shadow and multipath fading and enhanced robustness thanks to the insertion of the guard interval. In this paper, the authors introduced the principles of OFDM at first, then analysised the advantage and disadvantages of OFDM system, and finally discussed its application in contemporary high-speed communication systems, especially in wireless mobile networks.
