Effect of Carrier Frequency Offset on OFDM and Simulation Analysis

With the development of communication,especially wireless communication,the frequency resource is limited.So,new modulation techniques with robustness for multi-path delay spreading and new techniques for improving frequency utilization are needed.Orthogonal Frequency Division Multiplexing(OFDM) is one of the promising techniques that meet such requirements.The synchronization schemes in OFDM systems are studied in this thesis.The main contributions of this thesis include: the modeling of OFDM system and its advantages and disadvantages,simulation of the effect of carrier frequency offset on OFDM when the sub-channels are different by using of IDTF and DFT.
