【 摘 要 】

OFDM (Orthogonal Frequency Division Multiplexing) is one of the core technologies in the fourth generation mobile communication system. It is a widely-used method of the multi-carrier modulations based on IFFT and FFT transform, it can achieve the lowest complexity and effectively combat frequency selective fading. In this paper, we successfully use MATLAB to do the simulation of OFDM, and obtained good results, in which successful recovery out of the original signal under real channel condition, and error is less than 5% with the original signal.
